LOCP - locating pilus operons in Gram-positive bacteria

UNLABELLED Pilus operons encode a pivotal host-microbe interaction structure that is vital for pathogenicity, colonization and adhesion. LOCP is a computational tool to quickly test whether or not the genome of a gram-positive bacterium of interest or some DNA-contig in a metagenomic sample hold pilus operons. Predictions are made based on distinctive motifs of pilus-related protein sequences a...

Acyl enzyme intermediates in sortase-catalyzed pilus morphogenesis in gram-positive bacteria.

In gram-positive bacteria, covalently linked pilus polymers are assembled by a specific transpeptidase enzyme called pilus-specific sortase. This sortase is postulated to cleave the LPXTG motif of a pilin precursor between threonine and glycine and to form an acyl enzyme intermediate with the substrate. Pilus polymerization is believed to occur through the resolution of this intermediate upon s...

Bacteriocins of gram-positive bacteria.

In recent years, a group of antibacterial proteins produced by gram-positive bacteria have attracted great interest in their potential use as food preservatives and as antibacterial agents to combat certain infections due to gram-positive pathogenic bacteria. They are ribosomally synthesized peptides of 30 to less than 60 amino acids, with a narrow to wide antibacterial spectrum against gram-po...
