Figure 1. Normalized ellipticity at 210 nm as a function of the degree of neutralization (o ) for (1) sodium form of oligogalacturonates and polygalac-turonate (2) calcium form of galacturonates (O DP2, A DP4, DP5), (3) calcium form of the polygalacturonate (Ae taken as reference is the ellipticity of acid forms for each product open = sodium form filled = calcium form.)...

A second group of endo pectin lyases is characterized by optimum activity at slightly basic pH and by the ability to degrade polygalac-turonic acid (even though pectin is still favored). Sherwood 129) isolated this type of pectin lyase from Rhizoctonia solani. The enzyme had an optimal activity at pH 7.2 and degraded pectin faster than pectic acid. Bateman 128) found two pectin lyases from this microorganism which, when purified, were stimulated by cations and inhibited by EDTA. Optimal activity was between pH 8.0 and 9.0. [Pg.121]
