Multifunctional role of plant cysteine proteinases.

Cysteine proteinases also referred to as thiol proteases play an essential role in plant growth and development but also in senescence and programmed cell death, in accumulation of storage proteins such as in seeds, but also in storage protein mobilization. Thus, they participate in both anabolic and catabolic processes. In addition, they are involved in signalling pathways and in the response ...

Nematicidal effects of cysteine proteinases against sedentary plant parasitic nematodes.

Cysteine proteinases from the fruit and latex of plants, such as papaya, pineapple and fig, have previously been shown to have substantial anthelmintic efficacy, in vitro and in vivo, against a range of animal parasitic nematodes. In this paper, we describe the in vitro effects of these plant extracts against 2 sedentary plant parasitic nematodes of the genera Meloidogyne and Globodera. All the...

Cysteine proteinases and the pathogenesis of amebiasis.

Amebiasis is a major cause of morbidity and mortality throughout the tropical world. Entamoeba histolytica is now recognized as a separate species from the morphologically identical E. dispar, which cannot invade. Cysteine proteinases are a key virulence factor of E. histolytica and play a role in intestinal invasion by degrading the extracellular matrix and circumventing the host immune respon...

Labelling of cysteine proteinases in purified lysosomes.

NADH could not be freeze-stored at -25°C in 50 mMsodium phosphate buffer (pH range 6-8 20°C) without serious loss of the nucleotide; however, no losses were seen upon freeze storage in 50 mM-Hepes buffer (pH range 7-8, 20°C). The rate of NADH degradation was greater (approx. 2-fold) in 50 mMthan in 5 mM-sodium phosphate buffer, although NADH values at both buffer concentrations were similar (5%...

Benzyloxycarbonylphenylalanylcitrulline p-nitroanilide as a substrate for papain and other plant cysteine proteinases.

After preliminary assays, with papain, bromelain and ficin, on a range of citrulline p-nitroanilides, values of Km and kcat. for the papain-catalysed hydrolysis of three derivatives, N alpha- benzyloxycarbonylcitrulline p-nitroanilide, benzyloxycarbonylphenylalanylcitrulline p-nitroanilide and benzyloxycarbonylglycylphenylalanylcitrulline p-nitroanilide, were obtained. It is concluded that benz...
