hemD

This is an enzyme involved in the heme biosynthetic pathway. Also called uroporphyrinogen III synthase.

IISER_Bhopal 2021

Usage and Biology

During heme biosynthesis, this enzyme catalyses the asymmetric cyclization of linear tetrapyrrole to form a uroporphyrinogen III isomer. At the catalytic site, hydroxymethylbilane use as a substrate gives uroporphyrinogen III[1]. Reports have identified that along with hemA and hemL, upregulation of hemD and hemF increases the 5-Aminolevulinic acid accumulation which is a promising source for cancer treatment[2].
