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 …

The ABC transporters (also called traffic ATPases) make up a large superfamily of proteins
which share a common function and a common ATP-binding domain. ABC transporters are …

Three-dimensional structures have been elucidated for very few integral membrane
proteins. Computer methods can be used as guides for estimation of solute transport protein …

Escherichia coli LR05, in addition to producing MccB17, J25, and D93, secretes microcin L,
a newly discovered microcin that exhibits strong antibacterial activity against related …

The antibacterial peptide toxin colicin V uses a dedicated signal sequence-independent
system for its secretion in Escherichia coli and requires the products of three genes, cvaA …

Because of their potential usefulness as natural food preservatives, increased interest has
focused on bacteriocins from lactic acid bacteria. Mesentericin Y105 is a small non …

ABSTRACT A Tn 5 insertion in tolC eliminated microcin J25 production. The mutation had
little effect on the expression of the microcin structural gene and presumably acted by …

The gene coding for the immunity protein (mceB) and the structural gene of microcin E492
(mceA), a low-molecular-weight channel-forming bacteriocin produced by a strain of …

Microcin E492 is a polypeptide antibiotic that is produced and excreted by Klebsiella
pneumoniae RYC492. The genetic determinants for microcin synthesis and immunity were …

The ATP-binding cassette (ABC) transporters belong to a large superfamily of proteins which
share a common function and a common nucleotide-binding domain. The CvaB protein from …
