Identification
Name:Inosine triphosphate
DescriptionInosine triphosphate (ITP) is an intermediate in the purine metabolism pathway. ITPase is a cytosolic nucleoside triphosphate pyrophosphohydrolase specific for ITP catalysis to inosine monophosphate (IMP) and deoxy-inosine triphosphate (dITP) to deoxy-inosine monophosphate. ITPase's function is not clearly understood but possible roles for ITPase could be to prevent the accumulation of rogue nucleotides which would be otherwise incorporated into DNA and RNA, or compete with nucleotides such as GTP in signalling processes.

General function:
Involved in GTPase activity
Specific function:
May play a role in 30S ribosomal subunit biogenesis. Unusual circulary permuted GTPase that catalyzes rapid hydrolysis of GTP with a slow catalytic turnover. Dispensible for viability, but important for overall fitness. The intrinsic GTPase activity is stimulated by the presence of 30S (160-fold increase in kcat) or 70S (96 fold increase in kcat) ribosomes (PubMed:14973029). The GTPase is inhibited by aminoglycoside antibiotics such as neomycin and paromycin (PubMed:15466596) streptomycin and spectinomycin (PubMed:15828870). This inhibition is not due to competition for binding sites on the 30S or 70S ribosome (PubMed:15828870)
Gene Name:

Molecular weight:
