Description
The ASS1 is an enzyme called argininosuccinate synthase 1. This enzyme participates in the urea cycle, which is a sequence of chemical reactions that takes place in liver cells. The urea cycle processes excess nitrogen that is generated as the body uses proteins. The excess nitrogen is used to make a compound called urea, which is excreted from the body in urine. Recombinant human ASS1 protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques
