Gene: hisA Accession Numbers: EG10444 (MetaCyc), b2024, ECK2019

Species: Escherichia coli K-12 substr. MG1655

N-(5'-phospho-L-ribosyl-formimino)-5-amino-1-(5'-phosphoribosyl)-4-imidazolecarboxamide isomerase (HisA) carries out the fourth step in histidine biosynthesis.

HisA catalyzes an internal redox reaction known as an Amadori rearrangement [HennSax02].

Spontaneous hisA mutants were investigated [Jankovic90].
