Organism
Escherichia coli str. K-12 substr. MG1655 (strain: K-12, substrain: MG1655)
Lineage
Bacteria; Pseudomonadati; Pseudomonadota; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia
Also known as
ECK1777; gad; gap1
Summary
A gapA mutant is not in the Keio collection; gapA mutants were not expected to grow on the medium used to attempt to isolate them; gapA is not an essential gene (Baba, 2006). [More information is available at EcoGene: EG10367]. Escherichia coli is unusual in having two glyceraldehyde-3-phosphate dehydrogenases. [More information is available at EcoCyc: EG10367].
