Sulfur carrier protein ThiS adenylyltransferase (EC 2.7.7.73, thiF (gene)) is an enzyme with systematic name ATP:(ThiS) adenylyltransferase.[1][2][3][4] This enzyme catalyses the following chemical reaction

ATP + [ThiS] [math]\displaystyle{ \rightleftharpoons }[/math] diphosphate + adenylyl-[ThiS]

This enzyme binds Zn2+. The enzyme catalyses the adenylation of ThiS, a sulfur carrier protein involved in the biosynthesis of thiamine.
