Distinct physiological roles for the two l-asparaginase isozymes of Escherichia coli

•Escherichia coli contains two l-asparaginase isozymes with distinct localization, kinetics and regulation.•Mutant strains were used to examine the roles of these enzymes in l-asparagine utilization.•We report that l-asparaginase II permits growth on asparagine and glycerol under anaerobic condition...
