Autotransporters (ATs) are a family of bacterial proteins containing a C-terminal β-barrel-forming domain that facilitates the translocation of N-terminal passenger domain whose functions range from adhesion to proteolysis. Genetic replacement of the native passenger domain with heterologous proteins is an attractive strategy not only for applications such as biocatalysis, live-cell vaccines, a...
Filamentous phage such as M13 and fd consist of a circular, single-stranded DNA molecule surrounded by several different coat proteins. These phages have been used extensively as vectors in phage display where one of the phage coat proteins is genetically engineered to contain a unique peptide surface loop. Through these peptide sequences, a phage collection can be screened for individual phage...
UNLABELLED Peptides are useful tools for directing radioisotopes into tumors. We evaluated the ability of a bacterial peptide display system to isolate new prostate tumor-specific peptides. METHODS We used the bacterial FliTrx system to identify a new cyclic peptide that binds to prostate carcinoma. Serum stability and binding affinities of the (125)I-labeled peptide were tested. Furthermore,...
Novel cationic antimicrobial peptides typified by structures such as KKKKKKAAXAAWAAXAA-NH2, where X = Phe/Trp, and several of their analogues display high activity against a variety of bacteria but exhibit no hemolytic activity even at high dose levels in mammalian erythrocytes. To elucidate their mechanism of action and source of selectivity for bacterial membranes, phospholipid mixtures mimic...
