Abstract

Assays of CDP-glycerol:poly(glycerophosphate) glycerophosphotransferase (CGPTase) (EC 2.7.8.12) in membranes isolated from Bacillus subtilis 168 wild type and 11 strains bearing conditional lethal thermosensitive mutations in tagB, tagD, or tagF revealed that CGPTase deficiency was associated only with mutant tagF alleles. In vitro, thermosensitivity of CGPTase strongly suggests that the structural gene for this enzyme is tagF. We discuss apparent discrepancies between biochemical evidence favoring a membrane location for TagF and a previous report that suggested a cytoplasmic location based on sequence analysis.
