FunFam 198: Aminotransferase

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Arginine--pyruvate transaminase. [EC: 2.6.1.84]
L-arginine + pyruvate = 5-guanidino-2-oxopentanoate + L-alanine.
  • While L-arginine is the best substrate, the enzyme exhibits broad substrate specificity, with L-lysine, L-methionine, L-leucine, L-ornithine and L-glutamine also able to act as substrates, but more slowly.
  • Pyruvate cannot be replaced by 2-oxoglutarate as amino-group acceptor.
  • This is the first catalytic enzyme of the arginine transaminase pathway for L-arginine utilization in Pseudomonas aeruginosa.
  • This pathway is only used when the major route of arginine catabolism, i.e. the arginine succinyltransferase pathway, is blocked.
