Expression

EC Number Organism Comment Expression
2.3.1.32 Methanosarcina mazei expression of the abl operon is strictly salt dependent. Expression of ablA and ablB at the standard NaCl concentration of 38.5 mM is not detectable, but it increases drastically with increasing salt concentrations in the growth medium. The level of transcription of the abl operon is identical in cells grown with 400 or 800 mM NaCl up

2.3.1.32 malfunction DELTAabl mutants of Methanococcus maripaludis no longer produced Nepsilon-acetyl-beta-lysine and are incapable of growth at high salt concentrations, indicating that the abl operon is essential for Nepsilon-acetyl-beta-lysine synthesis Methanococcus maripaludis

2.3.1.264 physiological function pathway for the biosynthesis of Nepsilon-acetyl-beta-lysine based on genomic sequences Methanosarcina mazei
2.3.1.264 physiological function wild-type grows optimally at an NaCl concentration of 376.5 mM but tolerates NaCl concentrations up to 1 M. Growth of a mutant lacking AblA and AblB activities is indistinguishable from wild type at 376.5 mM NaCl. Growth of the mutant is severely inhibited at 800 mM NaCl and almost completely impaired at 1 M NaCl Methanococcus maripaludis
