Raffinose 102-111 hypothetical protein Escherichia coli 40-44 18008022-0 2007 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 Ile-391. Raffinose 37-46 hypothetical protein Escherichia coli 93-97 18008022-13 2007 Thus, we implicate residues in RafB that are responsible for raffinose transport and suggest that the substituted residues in RafB dictate structures that enhance transport of maltose. Raffinose 61-70 hypothetical protein Escherichia coli 31-35
