citrullus ecirrhosus/protease

Glyoxysomes are a subclass of peroxisomes involved in lipid mobilization. Two distinct peroxisomal targeting signals (PTSs), the C-terminal PTS1 and the N-terminal PTS2, are defined. Processing of the PTS2 on protein import is conserved in higher eukaryotes. The cleavage site typically contains a

A low molecular weight serine protease from seeds of Citrullus colocynthis was purified to electrophoretic homogeneity with high level of catalytic efficiency (22,945 M(-1) S(-1)). The enzyme was a monomer with molecular mass of 25 kDa estimated by SDS-PAGE. The enzyme was highly active over a pH

Glyoxysomal malate dehydrogenase (gMDH; EC 1.1.1.37) is synthesized by a reticulocyte system in the presence of watermelon mRNA (Citrullus vulgaris Schrad., var. Kleckey's Sweet No 6) as a cytosolic, higher-molecular-weight precursor (41 kdalton). We now show that this precursor is

Lectins are the heterogeneous proteins in plants that serve as storage proteins via defensive mechanisms against herbivores. In the current study, a lectin was extracted and purified from seeds of Citrullus colocynthis by Sepharose 4B-Galactose and DEAE-cellulose fast flow chromatographies.
