1.6 ANGSTROM CRYSTAL STRUCTURE OF ENTA-IM: A BACTERIAL IMMUNITY PROTEIN CONFERRING IMMUNITY TO THE ANTIMICROBIAL ACTIVITY OF THE PEDIOCIN-LIKE BACTERIOCIN, ENTEROCIN A
Overview
Many Gram-positive bacteria produce ribosomally synthesized antimicrobial, peptides, often termed bacteriocins. Genes encoding pediocin-like, bacteriocins are generally cotranscribed with or in close vicinity to a, gene encoding a cognate immunity protein that protects the, bacteriocin-producer from their own bacteriocin. We present the first, crystal structure of a pediocin-like immunity protein, EntA-im, conferring, immunity to the bacteriocin enterocin A. Determination of the structure of, this 103-amino acid protein revealed that it folds into an antiparallel, four-helix bundle with a flexible C-terminal part. The fact that the, immunity protein conferring immunity to carnobacteriocin B2 also consists, of a four-helix bundle (Sprules, T., Kawulka, K. E., and Vederas, J. C., (2004) ... [(full description)]
