一般描述
Lysyl PG is one of the predominant lipid constituents of gram-positive bacteria and Enterococcus faecalis.
应用
16:0 Lysyl PG is suitable for use:
- as a standard for lipidomics analysis by using three-dimensional hydrophilic interaction liquid chromatography-ion mobility-mass spectrometry (HILIC-IM-MS)
- to analyse the influence of peptides on the phase transition behavior of lipids by fourier transform infrared spectroscopy
- in the preparation of artificial vesicles modelled on the lipid composition of Staphylococcal membranes to study the effect of galloyl catechins
生化/生理作用
Lysyl phosphatidylglycerol (Lysyl-PG) is formed by lysinylation of PG in the presence of multiprotein resistance factor (MprF). MprF flips lysyl-PG from inner to outer membrane leaflet, increasing the positive charge on the membrane. Lysyl PG is essential for domain formation and antibiotic resistance.

Lysyl-phosphatidylglycerol (LPG) is a well-known membrane lipid in several gram-positive bacteria but is almost unheard of in gram-negative bacteria. In Staphylococcus aureus, the gene product of mprF is responsible for LPG formation. Low pH-inducible genes, termed IpiA, have been identified

Galloyl catechins, in particular (-)-epicatechin gallate (ECg), have the capacity to abrogate β-lactam resistance in methicillin-resistant strains of Staphylococcus aureus (MRSA); they also prevent biofilm formation, reduce the secretion of a large proportion of the exoproteome and induce profound changes
