abstract：:The primary structure of a bacteriocin produced by Enterococcus hirae DCH5 was determined by combined amino acid and DNA sequencing. Nucleotide analysis of a 2838-bp DNA fragment of E. hirae DCH5 revealed five putative ORFs. The first orf (hirJM79) encodes a 74-amino-acid peptide containing an N-terminal signal peptid...
