Hi Fateme,
No, Chimera cannot create a 3D structure from enzyme activity.

Probably you would to learn more about computational methods and on what information is available about your specific enzyme, then figure out the necessary steps of your project, and then find program(s) for each step. Several different programs might be required, but I don't know what they are.
Regards,
Elaine

Dear Sir/Madam,

I am looking for a program which could transform enzyme activity to a 3-dimentional form of the enzyme. I am not sure about such a program and I am not sure whether there is such program or not. I just saw the software for protein 3D structure visualization on your website and I assumed that this program might be useful. Could you please assist me in this case

Thank you in advance.
