The amino acid sequence of an extracellular nuclease of Staphylococcus aureus. 3. Complete amino acid sequence.
In a previous paper data were presented that permitted the linear arrangement of five fragments produced by cleavage of an extracellular nuclease of Staphylococcus aureus with cyanogen bromide (1). The amino acid sequences of the tryptic peptides prepared from these fragments, together with the partial sequences of chymotryptic peptides isolated from digests of the intact nuclease, have also be...
متن کاملPurification and characterization of LPXTGase from Staphylococcus aureus: the amino acid composition mirrors that found in the peptidoglycan.
Bacterial surface proteins are important molecules in the infectivity and survival of pathogens. Surface proteins on gram-positive bacteria have been shown to attach via a transpeptidase, termed sortase, that cleaves an LPXTG sequence found close to the C termini of nearly all surface proteins on these bacteria. We previously identified a unique enzyme (LPXTGase) from Streptococcus pyogenes tha...
متن کاملCloning and nucleotide sequencing of a Staphylococcus aureus gene encoding a branched-chain-amino-acid transporter.
We recently characterized a transposon-induced NaCl-sensitive mutant of Staphylococcus aureus (U. Vijaranakul, M. J. Nadakavukaren, D. O. Bayles, B. J. Wilkinson, and R. K. Jayaswal, Appl. Environ. Microbiol. 63:1889-1897, 1997). To further characterize this mutant, we determined the nucleotide sequence at the insertion site of the transposon on the S. aureus chromosome. Nucleotide sequencing r...
متن کاملAmino Acid Catabolism in Staphylococcus aureus and the Function of Carbon Catabolite Repression
Staphylococcus aureus must rapidly adapt to a variety of carbon and nitrogen sources during invasion of a host. Within a staphylococcal abscess, preferred carbon sources such as glucose are limiting, suggesting that S. aureus survives through the catabolism of secondary carbon sources. S. aureus encodes pathways to catabolize multiple amino acids, including those that generate pyruvate, 2-oxogl...
متن کاملGeneration of a vancomycin-intermediate Staphylococcus aureus (VISA) strain by two amino acid exchanges in VraS.
OBJECTIVES Staphylococcus aureus is a notorious bacterial pathogen and antibiotic-resistant isolates complicate current treatment strategies. We characterized S. aureus VC40, a laboratory mutant that shows full resistance to glycopeptides (vancomycin and teicoplanin MICs ≥32 mg/L) and daptomycin (MIC = 4 mg/L), to gain deeper insights into the underlying resistance mechanisms. METHODS Genomic...
