Identification
Name: Maltopentaose
Description:Maltopentaose is pentasaccaride or more specifically a pentasaccharide comprised of five D-glucose residues connected by alpha(1->4) linkages. It is a substrate for energy metabolism and carbon for Pseudomonas aeruginosa. Maltopentaose is imported into the cell via the maltooligosaccharide-specific LamB-channel of Pseudomonas aeruginosa (also called maltoporin). It is degraded by alpha amylase.
