Molybdopterin-synthase adenylyltransferase

Molybdopterin-synthase adenylyltransferase (EC 2.7.7.80, MoeB, adenylyltransferase and sulfurtransferase MOCS3) is an enzyme with systematic name ATP:molybdopterin-synthase adenylyltransferase.^[1][2] This enzyme catalyses the following chemical reaction

ATP + [molybdopterin-synthase sulfur-carrier protein]-Gly-Gly ${\displaystyle \rightleftharpoons }$ diphosphate + [molybdopterin-synthase sulfur-carrier protein]-Gly-Gly-AMP

This enzyme adenylates the C-terminus of the small subunit of the molybdopterin synthase.
