Glycopeptidolipid of Mycobacterium smegmatis J15cs Affects Morphology and Survival in Host Cells
Mycobacterium smegmatis has been widely used as a mycobacterial infection model. Unlike the M. smegmatis mc(2)155 strain, M. smegmatis J15cs strain has the advantage of surviving for one week in murine macrophages. In our previous report, we clarified that the J15cs strain has deleted apolar glycopeptidolipids (GPLs) in the cell wall, which may affect its morphology and survival in host cells. ...
متن کاملSynthesis of an unusual polar glycopeptidolipid in glucose-limited culture of Mycobacterium smegmatis.
There has been a general understanding that Mycobacterium smegmatis produces only apolar glycopeptidolipid (GPL), similar in structure to serovar non-specific GPL of Mycobacterium avium. In this study, synthesis of polar GPL in carbon-starved M. smegmatis is reported. Mass spectrometric analysis suggests the polar GPL to be a hyperglycosylated species. The earlier structural studies of polar GP...
متن کاملA GMC Oxidoreductase Homologue Is Required for Acetylation of Glycopeptidolipid in Mycobacterium smegmatis
The Mycobacterium tuberculosis Rv3409c gene is required for modulation of the Toll-like receptor 2 (TLR-2) signaling response in infected macrophages. Although each is annotated as encoding a cholesterol oxidase, neither Rv3409c nor its ortholog MSMEG1604 is required for the metabolism of cholesterol in mycobacteria. Here we report that a unique lipid, L1334, accumulates in a MSMEG1604 transpos...
متن کاملHyperglycosylation of glycopeptidolipid of Mycobacterium smegmatis under nutrient starvation: structural studies.
The presence of a polar species of glycopeptidolipid (GPL) in carbon-starved Mycobacterium smegmatis has been reported previously. In this study, the complete structure of this GPL is established with the help of MALDI-TOF (matrix assisted laser desorption/ionization time of flight) and ESI (electrospray ionization) -MS, (13)C-SEFT (spin echo Fourier transform) -NMR spectroscopy, and HPLC analy...
