It is a substrate for energy metabolism and carbon for E. coli. Maltopentaose is imported into the cell via the maltooligosaccharide-specific LamB-channel of Escherichia coli (also called maltoporin). It is degraded by alpha amylase. a-D-GLCP-(1RIght4)-a-D-GLCP-(1Right4)-a-D-GLCP-(1Right4)-a-D-GLCP-(1Right4)-D-GLC
