HMDB Protein ID HMDBP11841
Secondary Accession Numbers None
Name Methylthioribulose-1-phosphate dehydratase
  1. MTRu-1-P dehydratase
  2. APAF1-interacting protein
  3. hAPIP
Gene Name APIP
Protein Type Unknown
Biological Properties
General Function Not Available
Specific Function Catalyzes the dehydration of methylthioribulose-1-phosphate (MTRu-1-P) into 2,3-diketo-5-methylthiopentyl-1-phosphate (DK-MTP-1-P). Functions in the methionine salvage pathway, which plays a key role in cancer, apoptosis, microbial proliferation and inflammation. May inhibit the CASP1-related inflammatory response (pyroptosis), the CASP9-dependent apoptotic pathway and the cytochrome c-dependent and APAF1-mediated cell death.
  • Cysteine and methionine metabolism
