Abstract

An nlp (Ner like protein) gene from E. coli was previously cloned and sequenced. Here we show that expression of the sugar metabolism related genes, lacZ, malQ and malP, increased 2.5-to 8.3-fold in the presence of a plasmid containing the nlp gene. This suggested that the nlp gene could induce maltose- and lactose-metabolism coordinately with crp*1 in the absence of cAMP. Using the nlp-lacZ fusion gene, it was possible to show the promoter of nlp was active in vivo.
