00:01 | Hello everyone. Welcome to this tutorial on Build and Modify Process Diagram in CellDesigner. |
00:08 | In this tutorial, we will learn to: use Macros , move Components on the draw area , connect a reaction line around a species, |
00:18 | align and extend a reaction line , add a Product and a Reactant. |
00:23 | For this tutorial, I am usingUbuntu Linux OS 14.04, CellDesigner version 4.3, Java version 1.7. |
00:35 | To follow this tutorial, learners should be familiar with: undergraduate Biochemistry, CellDesigner interface. |
00:43 | If not, for relevant CellDesigner tutorials, please visit the Spoken Tutorial website. |
00:51 | Let us begin. |
00:53 | What you see here is the conventional diagram for Alanine Biosynthesis. |
00:58 | Now, we’ll use CellDesigner to create this process diagram. |
01:02 | Open the terminal by pressing Ctrl+Alt+T keys simultaneously. |
01:09 | Now type: ./runCellDesigner4.3 and press Enter. |
01:20 | CellDesigner window is now open on your terminal. |
01:24 | Open a new file by pressing CTRL+N and name it Build and Modify Process Diagram. |
01:34 | Keep the default width and height and click on the Ok button. |
01:39 | Now let us learn what are ‘Macros’. |
01:42 | Macros are frequently used Components sets that help in drawing the diagrams easily. |
01:47 | On the toolbar, click on the Macros icon for Catalysis and click on the draw area. |
01:57 | We now have a Macros-Catalysis reaction on the draw area. |
02:02 | Let’s learn to move all the components to another side of the draw area. |
02:08 | For that, click on the Edit menu and then click on 'Select All'. |
02:16 | Alternately, you may press Ctrl + A keys. |
02:21 | All the Components are now highlighted. |
02:24 | Now, click anywhere on the highlighted components and drag them to the desired location. |
02:30 | Let's proceed. |
02:32 | Click anywhere on the draw area to uncheck the highlighted components. |
02:37 | Again, on the draw area, right click on the Generic Protein S1. |
02:43 | Then click on the option 'Change Identity'. |
02:47 | In the 'class' box, change the Protein to Simple Molecule. |
02:53 | Type the Name as: 2-keto-isovalerate. |
02:58 | And then click on the ‘Apply’ button. |
03:02 | In the dialog box ‘The Same Species Exists’, click ‘No’. |
03:10 | However, if you want to reflect the change to all components of the species, click ‘Yes’. Here, I will click ‘No’. |
03:20 | Observe the Generic Protein S1 is now a simple molecule named 2-keto-isovalerate. |
03:30 | I will drag the molecule to accomodate the name. |
03:34 | Right-click in the center of the end-point Generic protein-S1 which is a product. |
03:42 | Change identity to Simple Molecule and name it Valine. |
03:50 | Click on the Apply button. |
03:52 | You have Valine on the draw area. |
03:36 | Next, rename catalyst S2. Right-click on it and select Edit Protein. |
04:06 | In the ‘name’ field, type Aminotransferase. |
04:11 | Click on Update and close the dialog box. |
04:16 | Drag the corner of the molecule to accomodate the name. |
04:21 | Next, let’s change the position of the linked reaction. |
04:25 | Click in the center of the 'end-point species i.e. Valine and drag and drop at the desired location. |
04:33 | Repeat the same with Aminotransferase. |
04:37 | Observe that the linked reaction follows wherever the ‘end-point’ Species moves. |
04:44 | We will now learn how to connect a reaction line around a species. |
04:49 | A Reaction line can be connected to any of the 16 connection points around a Species. |
04:56 | I will show you how to do so. |
04:59 | Open a new window by pressing CTRL+N. |
05:04 | Name this file as Connection points. |
05:08 | Keep the default width and height and click on OK button. |
05:14 | On the draw area, draw two generic proteins and name them Protein 1 and Protein 2. |
05:23 | In the main menu, click on the icon for State Transition. |
05:28 | Then, on the draw area, hover the mouse on ‘start-point' Species, Protein 1. |
05:36 | Observe that all 16 connection points are highlighted in grey color. |
05:42 | Note that when the cursor is pointed to one of these connection points, it will change to blue color. |
05:49 | Let’s click on one of the connection points. |
05:53 | In the same manner, hover the mouse on the ‘end-point' Species i.e. Protein 2. |
06:00 | Again, as explained above, click on the required connection point. |
06:05 | A State Transition reaction line is formed between the selected connection points. |
06:12 | Next, we will align the Reaction line. |
06:16 | Click on the State transition reaction line between Protein 1 and Protein 2 |
06:21 | Note that the 2 process nodes on the reaction line get highlighted. |
06:27 | If we hover the mouse on either of the 2 process nodes, a plus sign appears. |
06:34 | Click on one of the process nodes. |
06:37 | Now drag and place the pointer on the preferred connection point. |
06:43 | Click anywhere on the draw area to uncheck the highlighted components. |
06:49 | To extend or stretch the reaction line, first click on it. |
06:54 | Now click on either of the process nodes located on the start-point or end-point Species. |
07:01 | Drag the mouse to stretch the reaction line till the preferred connection point. |
07:07 | From here on, we will proceed with the Process diagram. |
07:12 | Let us come back to the Build and Modify Process Diagram window. |
07:16 | Let’s add a Reactant and a Product to the existing reaction. |
07:21 | From the toolbar, click and place 2 simple molecules on the draw area. |
07:27 | Name them Glutamate and 2-Oxoglutarate. |
07:36 | Drag and place them adjacent to the Simple molecules: 2-keto-isovalerate and Valine. |
07:44 | As explained earlier, let us align the components on the draw area. |
07:49 | From what was explained earlier, I have now completed aligning the components. |
07:55 | On the toolbar, click on the icon for ‘Add Product’. |
08:00 | Now hover the mouse on the State Transition reaction between 2-keto-isovalerate and Valine. |
08:07 | Click on the highlighted process node. |
08:10 | Next, hover the mouse on 2-Oxoglutarate. |
08:17 | Click on any one of the 16 highlighted process nodes. |
08:21 | Observe, a reaction line appears between State Transition and 2-Oxoglutarate. |
08:29 | Similarly, click on ‘Add Reactant’ icon. |
08:34 | Hover the mouse on Glutamate and click on one of the 16 highlighted process nodes. |
08:40 | Next, hover the mouse on the State Transition reaction and click on the process node. |
08:49 | Observe, a reaction line appears between State Transition and Glutamate. |
08:55 | We now have a complete Catalysis reaction with a Reactant and a Product. |
09:01 | I will align the reaction to accommodate other components in the process diagram. |
09:09 | From the toolbar, use the icons: State Transition , Simple Molecule, Generic Protein and Catalysis. |
09:18 | This is the completed process diagram. |
09:22 | To view it properly, go to View on the main menu bar and click on Zoom Fit |
09:32 | You now see the completed Process Diagram |
09:36 | Let us summarize. In this tutorial, we have learnt: to use Macros, |
09:42 | move Components on the draw area , connect a reaction line around a species, |
09:48 | align and extend a reaction line, add a Product and a Reactant. |
