Guanine deaminase also known as cypin, guanase, guanine aminase, GAH, and guanine aminohydrolase is an aminohydrolase enzyme which converts guanine to xanthine. [5] [6] [7] Cypin is a major cytosolic protein that interacts with PSD-95. It promotes localized microtubule assembly in neuronal dendrites. [8]

N-acetylglucosamine-6-sulfatase

N-acetylglucosamine-6-sulfatase also known as glucosamine (N-acetyl)-6-sulfatase is an enzyme that in humans is encoded by the GNS gene. This enzyme is deficient in Sanfilippo Syndrome type IIId. This enzyme catalyses the following chemical reaction:

GMP synthase

Guanosine monophosphate synthetase, also known as GMPS is an enzyme that converts xanthosine monophosphate to guanosine monophosphate.

Amidophosphoribosyltransferase

Amidophosphoribosyltransferase (ATase), also known as glutamine phosphoribosylpyrophosphate amidotransferase (GPAT), is an enzyme responsible for catalyzing the conversion of 5-phosphoribosyl-1-pyrophosphate (PRPP) into 5-phosphoribosyl-1-amine (PRA), using the amine group from a glutamine side-chain. This is the committing step in de novo purine synthesis. In humans it is encoded by the PPAT gene. ATase is a member of the purine/pyrimidine phosphoribosyltransferase family.
