Product information "ansA, Recombinant, E. coli, aa1-338, His-tag (Cytoplasmic L-asparaginase I, ECK1765, JW1756)"
AnsA is the cytoplasmic asparaginase from Escherichia coli involved in intracellular asparagine utilization. Escherichia coli possesse two l-asparaginases: the cytoplasmic type I form (ansA) and the periplasmic type II form (ansB). AnsA (Type I asparaginase) is constitutively expressed and required for the growth of the bacteria on asparagine as the sole nitrogen source. Purified by using conventional chromatography techniques. Source: Recombinant corresponding to aa1-338 ansA, fused to His-tag at N-terminus, expressed in E.coli.
