What is A cofactor requirement for polygalacturonase from Cuscuta campestris about?

The occurrence of a polygalacturonase in tissue of Cuscuta is reported. The enzyme activity requires the presence of a cofactor, which can be removed by dialysis. The cofactor is heat stable and extractable in 80% methanol or in petroleum ether. It appears to be a low molecular weight peptide, since its activity is lost on incubation with proteinase K or papain. The exact nature and the possible function of this co-factor in the breakdown of pectins by Cuscuta are under investigation.
