Reference Data
Summary	Escherichia coli possesse two l-asparaginases: the cytoplasmic type I form (ansA) and the periplasmic type II form (ansB). AnsA is involved in intracellular asparagine utilization. AnsA (Type I asparaginase) is constitutively expressed and required for the growth of the bacteria on asparagine as the sole nitrogen source.
