    Protein Summary

    The TM0655 gene of Thermotoga maritima encodes an S-adenosylmethionine decarboxylase (AdoMetDC) (EC AdoMetDC is a pyruvoyl-dependent amino acid decarboxylase involved in methionine metabolism and the polyamine biosynthetic pathway. The TM0655 structure reveals the relationship between the prokaryotic and eukaryotic versions of the enzyme (1) with the former presenting a dimeric fold very similar to the eukaryotic AdoMetDC protomer, suggesting an evolutionary link (1) . There is no detectable sequence similarity between the AdoMetDC found in eukaryotes and prokaryotes, except at the site of pyruvoyl group formation, where the key active site residues involved in substrate binding, catalysis and proenzyme processing are structurally conserved (1).
