>gnl|CDD|29604 cd00494, HMBS, Hydroxymethylbilane synthase (HMBS), also known as porphobilinogen deaminase (PBGD), is an intermediate enzyme in the biosynthetic pathway of tetrapyrrolic ring systems, such as heme, chlorophylls, and vitamin B12. HMBS catalyzes the conversion of porphobilinogen (PBG) into hydroxymethylbilane (HMB). HMBS consists of three domains, and is believed to bind substrate through a hinge-bending motion of domains I and II. HMBS is found in all organisms except viruses.. Length = 292
