DNA/RNA

Transcription

2212 bp mRNA; ORF: 2081 bp

Proteins

Description

693 amino acids; 76 kDa;there are two variant forms of human GMP synthetase; homodimerization; GMP synthetase contains two functional domains: a glutamine amidotransferase (glutaminase domain, with a conserved Cys-His-Glu triad), responsible for glutamine hydrolysis, and a synthetase domain; responsible for ATP hydrolysis and GMP formation

Expression

higher in proliferating, transformed cells than in nontransformed cells; in normal cells, higher expression in fibroblasts, followed by bone marrow, leukocytes, erythrocytes, placenta, and liver

Localisation

cytoplasmic

Function

enzyme of the de novo synthesis of guanine nucleotides: amidotransferase that catalyzes the amination of xanthosine 5 prime monophosphate to form GMP in the presence of ATP and glutamine; GTP is also involved in many enzymatic reactions important for cell division.
