MetaCyc Reaction: 2.7.7.80

Superclasses: Reactions Classified By Conversion Type Simple Reactions Chemical Reactions Protein-Modification Reactions
Reactions Classified By Substrate Macromolecule Reactions Protein-Reactions Protein-Modification Reactions

EC Number: 2.7.7.80

Enzymes and Genes:

Escherichia coli K-12 substr. MG1655 : molybdopterin-synthase adenylyltransferase Inferred from experiment : moeB
Homo sapiens : MOCS3 adenylyltransferase/sulfurtransferase : MOCS3

In Pathway: molybdenum cofactor biosynthesis

The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.

Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.

Mass balance status: Balanced.

Enzyme Commission Primary Name: molybdopterin-synthase adenylyltransferase

Enzyme Commission Synonyms: MoeB, adenylyltransferase and sulfurtransferase MOCS3

Standard Gibbs Free Energy (ΔrG in kcal/mol): -168.60596 Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
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. The reaction occurs in prokaryotes and eukaryotes. 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.
