FunFam 440: dTDP-4-amino-4,6-dideoxy-D-glucose ammonia-lyase

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.

DTDP-4-amino-4,6-dideoxy-D-glucose ammonia-lyase. [EC: 4.3.1.30]
dTDP-4-amino-4,6-dideoxy-alpha-D-glucopyranose + S-adenosyl-L-methionine + reduced acceptor = dTDP-3-dehydro-4,6-dideoxy-alpha-D-glucopyranose + NH(3) + L-methionine + 5'-deoxyadenosine + acceptor.
  • The enzyme, which is a member of the 'AdoMet radical' (radical SAM) family, is involved in biosynthesis of TDP-alpha-D-desosamine.
  • The reaction starts by the transfer of an electron from the reduced form of the enzyme's [4Fe-4S] cluster to S-adenosyl-L-methionine, spliting it into methionine and the radical 5-deoxyadenosin-5'-yl, which attacks the sugar substrate.
