- Phosphoribosylamine-glycine ligase
In
enzymology , a phosphoribosylamine-glycine ligase (EC number|6.3.4.13) is anenzyme that catalyzes thechemical reaction :ATP + 5-phospho-D-ribosylamine + glycine ADP + phosphate + N1-(5-phospho-D-ribosyl)glycinamide
The 3 substrates of this enzyme are ATP,
5-phospho-D-ribosylamine , andglycine , whereas its 3 products are ADP,phosphate , andN1-(5-phospho-D-ribosyl)glycinamide .This enzyme belongs to the family of
ligase s, specifically those forming generic carbon-nitrogen bonds. The systematic name of this enzyme class is 5-phospho-D-ribosylamine:glycine ligase (ADP-forming). Other names in common use include phosphoribosylglycinamide synthetase, glycinamide ribonucleotide synthetase, phosphoribosylglycineamide synthetase, glycineamide ribonucleotide synthetase, 2-amino-N-ribosylacetamide 5'-phosphate kinosynthase, 5'-phosphoribosylglycinamide synthetase, and GAR. This enzyme participates inpurine metabolism .Bacterial genes that encode this enzyme are often named "purD".
tructural studies
