Orn_Arg_deC_N

Orn_Arg_deC_N
PFAM accession number:PF02784
Interpro abstract (IPR022644):

These enzymes are collectively known as group IV decarboxylases [ (PUBMED:8181483) ]. Pyridoxal-dependent decarboxylases acting on ornithine, lysine, arginine and related substrates can be classified into two different families on the basis of sequence similarities [ (PUBMED:3143046) (PUBMED:8181483) ]. Members of this family while most probably evolutionary related, do not share extensive regions of sequence similarities. The proteins contain a conserved lysine residue which is known, in mouse ODC [ (PUBMED:1730582) ], to be the site of attachment of the pyridoxal-phosphate group. The proteins also contain a stretch of three consecutive glycine residues and has been proposed to be part of a substrate- binding region [ (PUBMED:2198270) ].
