Also known as
ECK3738
Summary
AsnA and AsnB are redundant; an asparagine auxotrophy requires that both genes be mutated. [More information is available at EcoGene: EG10091]. Asparagine synthetase A (AsnA) is one of two asparagine synthetases in Escherichia coli, catalyzing the ammonia-dependent conversion of aspartate to asparagine. [More information is available at EcoCyc: EG10091].
