FunFam 136177: Cysteine synthase A protein

There are 2 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
Cysteine synthase. [EC: 2.5.1.47]
O-acetyl-L-serine + hydrogen sulfide = L-cysteine + acetate.
  • Some alkyl thiols, cyanide, pyrazole and some other heterocyclic compounds can act as acceptors.
  • Not identical with EC 2.5.1.51, EC 2.5.1.52 and EC 2.5.1.53.
  • Formerly EC 4.2.99.8.

Malonyl-[acyl-carrier protein] O-methyltransferase. [EC: 2.1.1.197]
S-adenosyl-L-methionine + malonyl-[acyl-carrier protein] = S-adenosyl-L- homocysteine + malonyl-[acyl-carrier protein] methyl ester.
  • Involved in an early step of biotin biosynthesis in Gram-negative bacteria.
  • This enzyme catalyzes the transfer of a methyl group to the omega- carboxyl group of malonyl-[acyl-carrier protein] forming a methyl ester.
  • The methyl ester is recognized by the fatty acid synthetic enzymes, which process it via the fatty acid elongation cycle to give pimelyl- [acyl-carrier-protein] methyl ester.
  • While the enzyme can also accept malonyl-CoA, it has a much higher activity with malonyl-[acyl-carrier protein].
