title: Cloning and sequencing of an Escherichia coli gene, nlp, highly homologous to the ner genes of bacteriophages Mu and D108.
abstract: An nlp (Ner-like protein) gene was isolated from Escherichia coli. The nucleotide sequence of a 1,342-base-pair chromosomal DNA fragment containing the nlp gene was analyzed. It contained two open reading frames; one encoded 91 amino acid residues with an Mr of 10,361, and the other (ORFX) encoded 131 amino acid residues of the carboxyl-terminal region of a truncated polypeptide. The amino acid sequence deduced from the DNA sequence of nlp was highly homologous (62 to 63%) to the Ner proteins of bacteriophages Mu and D108. The amino-terminal region of Nlp deduced from the complete open reading frame contained a presumed DNA-binding region. The nlp gene was located at 69.3 min on the E. coli genetic map.
