DOI: 10.1002/2211-5463.13490
Abstract: Hydroxymethylbilane synthase (HMBS) is the third enzyme involved in haem biosynthesis, in which it catalyses the formation of tetrapyrrole 1‐hydroxymethylbilane (HMB). In this process, HMBS binds four consecutive substrate molecules, creating the enzyme‐intermediate complexes ES,… read more here.

DOI: 10.1007/s10545-018-0163-6
Abstract: Acute intermittent porphyria (AIP), an autosomal dominant disorder due to the half-normal activity of hydroxymethylbilane synthase (HMBS), is characterized by acute neurovisceral attacks that are precipitated by factors that induce heme biosynthesis. Molecular diagnosis is… read more here.

DOI: 10.1038/s41591-018-0199-z
Abstract: Acute intermittent porphyria (AIP) results from haploinsufficiency of porphobilinogen deaminase (PBGD), the third enzyme in the heme biosynthesis pathway. Patients with AIP have neurovisceral attacks associated with increased hepatic heme demand. Phenobarbital-challenged mice with AIP… read more here.

DOI: 10.1080/20009666.2017.1317535
Abstract: ABSTRACT Acute intermittent porphyria (AIP) is a rare autosomal dominant hepatic porphyria due to deficiency of hydroxymethylbilane synthase (HMBS), also known as porphobilinogen deaminase leading to accumulation of porphyrin precursors. However, gene defect alone is… read more here.
