Critical Role of Zinc in a New Murine Model of Enterotoxigenic Escherichia coli Diarrhea.

abstract：:Inactivation of sortase gene srtA in Streptococcus pneumoniae strain R6 caused the release of beta-galactosidase and neuraminidase A (NanA) from the cell wall into the surrounding medium. Both of these surface proteins contain the LPXTG motif in the C-terminal domain. Complementation with plasmid-borne srtA reversed p...
