The pH optima of these activities were 6·0, 6·5 and 5·7 respectively. Monogalacturonic acid and another unidentified product accumulated during the degradation of polygalacturonic acid.}, number={1}, journal={PHYTOCHEMISTRY}, author={HUNTER, WJ and ELKAN, GH}, year={1975}, pages={107–110} }

A four step procedure was developed producing a 44-fold increase in specific activity with 9% recovery. The enzyme was found to rapidly degrade pectic acid but not pectin. No transeliminase activity was detected. Viscosity and per cent hydrolysis studies formed a basis for suggesting that this enzyme cleaves its substrate in a random manner and is likely to be an endopolygalacturonase.}, number={12}, journal={PHYTOCHEMISTRY}, author={HUNTER, WJ and ELKAN, GH}, year={1974}, pages={2725–2727} }
