Bacteroides thetaiotaomicron strain 217 can use pectins as a sole carbon source. Preliminary characterization of the pectinolytic enzymes revealed three complementary activities in this strain: a pectin methylesterase (PME), a pectate lyase (PL) and a polygalacturonase (PG), which were all inducible by pectin or polygalacturonate.
Pectate lyase (EC 4.2.2.2) is an enzyme involved in the maceration and soft rotting of plant tissue. Pectate lyase is responsible for the eliminative cleavage of pectate, yielding oligosaccharides with 4-deoxy-α-D-mann-4-enuronosyl groups at their non-reducing ends. The protein is maximally expressed late in pollen development.
