PurM (Aminoimidazole Ribonucleotide [AIR] synthetase), one of eleven enzymes required for purine biosynthesis, catalyzes the conversion of formylglycinamide ribonucleotide (FGAM) and ATP to AIR, ADP, and Pi, the fifth step in de novo purine biosynthesis. The N-terminal domain of PurM is related to the ATP-binding domains of hydrogen expression/formation protein HypE, the AIR synthases, selenophosphate synthetase (SelD), and FGAM synthase and is thought to bind ATP.

ThiL (Thiamine-monophosphate kinase) plays a dual role in de novo biosynthesis and in salvage of exogenous thiamine. Thiamine salvage occurs in two steps, with thiamine kinase catalyzing the formation of thiamine phosphate, and ThiL catalyzing the conversion of this intermediate to thiamine pyrophosphate. The N-terminal domain of ThiL binds ATP and is related to the ATP-binding domains of hydrogen expression/formation protein HypE, the AIR synthases, FGAM synthase and selenophosphate synthetase (SelD).

hydrogenase expression/formation protein HypE; This family contains HypE (or HupE), a protein required for expression of catalytically active hydrogenase in many systems. It appears to be an accessory protein involved in maturation rather than a regulatory protein involved in expression. HypE shows considerable homology to the thiamine-monophosphate kinase ThiL (TIGR01379) and other enzymes.

4.62e-08
PurL subunit of the formylglycinamide ribonucleotide amidotransferase (FGAR-AT), first repeat. FGAR-AT catalyzes the ATP-dependent conversion of formylglycinamide ribonucleotide (FGAR) and glutamine to formylglycinamidine ribonucleotide (FGAM), ADP, phosphate, and glutamate in the fourth step of the purine biosynthetic pathway. In eukaryotes and Gram-negative bacteria, FGAR-AT is encoded by the purL gene as a multidomain protein with a molecular mass of about 140 kDa. In Gram-positive bacteria and archaea FGAR-AT is a complex of three proteins: PurS, PurL, and PurQ. PurL itself contains two tandem N- and C-terminal domains (four domains altogether). The N-terminal domains bind ATP and are related to the ATP-binding domains of HypE, ThiL, SelD and PurM.
