M-CSA Mechanism and Catalytic Site Atlas

Camphor 5-monooxygenase (M-CSA:133)

Proteins that are close homologues to the M-CSA reference protein and have the same catalytic residues (highlighted in green, below) probably share the same mechanism. Please also check if the homologue shares the same FunTree Structural Cluster and the same Pfam family, as another measure of similarity.

Legend:
Reference Residue Conserved Residue Non Conserved Residue Outside Alignment Reference Residue not in this chain

The residue id shown is the one in the PDB sequence. This may be different from the resid given by the author of the PDB file.

PDB sequences identical to 1yrc

In these PDB chains all the catalytic residues are conserved and have the same numbering as the reference.
