Temperature-induced Changes in Hill Activity of Chloroplasts Isolated from Chilling-sensitive and Chilling-resistant Plants.

abstract：:An enzyme with fatty acid alpha-oxidation activity (49 nkat mg(-1); substrate: lauric acid) was purified from germinating pea (Pisum sativum) by a five-step procedure to apparent homogeneity. The purified protein was found to be a 230-kD oligomer with two dominant subunits, i.e. a 50-kD subunit with NAD(+) oxidoreduct...
