The synthesis of OmpM (apparent M r 43000) and transport of maltose into cells of Y. enterocolitica were induced by maltose and maltodextrins. A mutant lacking OmpM was drastically impaired in maltose transport, independent of induction by maltose. The MBP of Y. enterocolitica (apparent M r 40000) was found in the osmotic shock fluid. Its synthesis was induced by maltose. Moreover, rabbit antibodies raised against the MBP of E. coli cross-reacted with the analogous protein from Y. enterocolitica. The MBP of Y. enterocolitica restored the maltose transport activities in ΔmalE mutant cells of E. coli. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-139-2-195
