Proteolytic activity associated with the cell wall by Gómez, L.D, Casano, L.M, Rouby, M.B., Buckeridge, M.S, Trippi, V.S

“…Significant endopeptidase activity was observed at acid pH, becoming maximalat pH 4 5 Moreover, an endopeptidase (EP) with similar pH optimum, wasisolated from EF by affinity chromatography on haemoglobin-agarose gel Theisolated enzyme showed high thermal and temporal stability and dependence onmetal cofactors, EP seems to be a monomeric enzyme with apparent mol massof 52 kDa and it could hydrolyze several extracellular soluble polypeptides AcidicEP activity increased during hypocotyl growth, reaching its highest value duringthe exponential phase of the elongation, and then decreased It is proposed thatthe EP could be involved in the regulation of cell wall elongation.…”

Valoración de la actividad colinesterasica plasmática en la vigilancia epidemiológica de población expuesta a pesticidas by PAVIOTTI, FABIAN DANIEL, GUGLIELMONE, RICARDO

“…The result of the determinations gave significant differences with values of plasmatic cholinesterase activity in rural areas lower than the registered in an urban population of men and women.Owing to the marked individuality of the cholinesterase enzyme the percentage of inhibition were determined as significant and very significant compatible with the exposition to pesticides inhibiting the cholinesterase (Delta Check).Beside, intervals of reference were calculated in particular for the enzyme so as to be able to observe an adequate epidemiologic surveillance. …”

Differential salt-stress response during germination and vegetative growth in in vitro selected somaclonal mutants of Cenchrus ciliaris L. by E. López Colomba; E.Tomassino; C. Luna; S. Griffa; E. Carloni; A. Ribotta; M. Quiroga; K. Grunberg

“…<br />S6 had the highest growth rate, indicating its potential tolerance to salt stress, whereas M10 was the most sensitive, with Bi, S4 and S1 being intermediate tolerant genotypes. Catalase enzyme activity (CAT) in M10 decreased in response to salt stress and was significantly associated with malondialdehide content, suggesting salt injury, whereas higher levels of CAT activity in S6 during salt stress were associated with increased salinity tolerance. …”
