WebOct 3, 2016 · It is also a source of phosphatidyl and of sn -glycerol-1-phosphate groups [ 134 ]. It is not clear what the physical behaviour of many of these derivatives is; however, the charge carried may be net 0 or even positive (e.g., lysyl-PG), implying that the charge of this lipid may be modulated by such elaborations. WebHowever, they are known for producing aminoacylated phosphatidylglycerol (PG), especially positively charged L-lysyl-PG, which is catalyzed by lysyl-PG synthase MprF, which appears to have a broad range of specificity for L-aminoacyl transfer RNAs. ...
