ABSTRACT We cloned a gene, sugE, from the chromosome of Enterobacter cloacae ATCC 13047. Analysis of the susceptibilities of the sugE-containing strain (Escherichia coli KAM32/pSUGE28) and… Expand
Amino Acids that Confer Transport of Raffinose and Maltose Sugars in the Raffinose Permease (RafB) of Escherichia coli as Implicated by Spontaneous Mutations at Val-35, Ser-138, Ser-139, Gly-389 and…
