Each day Apimba highlights one enzyme from our curated database of biochemical catalysts. The selection is deterministic for the day, so everyone sees the same enzyme until midnight UTC.
EC Number: 2.7.7.80
Reaction: ATP + [molybdopterin-synthase sulfur-carrier protein]-Gly-Gly = diphosphate + [molybdopterin-synthase sulfur-carrier protein]-Gly-Gly-AMP
Systematic name: ATP:molybdopterin-synthase adenylyltransferase
Other names: MoeB; adenylyltransferase and sulfurtransferase MOCS3
Comments: Adenylates the C-terminus of the small subunit of the molybdopterin synthase. This activation is required to form the thiocarboxylated C-terminus of the active molybdopterin synthase small subunit. The reaction occurs in prokaryotes and eukaryotes. In the human, the reaction is catalysed by the N-terminal domain of the protein MOCS3, which also includes a molybdopterin-synthase sulfurtransferase (EC 2.8.1.11) C-terminal domain.
