   2.4.1.337 | physiological function |
the abnormal morphology of a UgtP mutant is caused by lack of glucolipids. Expression of a monoglucosyldiacylglycerol produced by 1,2-diacylglycerol 3-glucosyltransferase from Acholeplasma laidlawii (alMGS) almost completely suppresses the UgtP disruptant phenotype. Activation of extracytoplasmic function sigmas (SigM, SigV, and SigX) in the UgtP mutant is decreased by alMGS expression, and is suppressed to low levels by MgSO4 addition. When alMGS and Acholeplasma laidlawii 1,2-diacylglycerol-3-glucose (1->2)-glucosyltransferase producing diglucosyldiacylglycerol are simultaneously expressed, SigX activation is repressed to wild type level |
