Modularity of methylotrophy, revisited.

abstract：:Sulphoquinovosyldiacylglycerols (SQDG) are polar sulphur-containing membrane lipids, whose presence has been related to a microbial strategy to adapt to phosphate deprivation. In this study, we have targeted the sqdB gene coding the uridine 5'-diphosphate-sulphoquinovose (UDP-SQ) synthase involved in the SQDG biosynth...
