Acid carboxypeptidases: their occurrence in plants, intracellular distribution and possible function.

چکیده
Saure Carhoxypeptidase, welche Phenylalanin von CbO-Leu-Phe-OH bei pH 5,3 abspaltet, ist ein in höheren Angiospermen weit verbreitetes Enzym. Es scheint dagegen in primitiven Angiospermen (Fagus und Magnolia) sowie in Gymnospermen und Kryptogamen (Ausnahme: Equisetum) zu fehlen. Bei Zitrone ist die Aktivität saurer Carboxypeptidase von Natur und Alter der extrahierten Gewebe abhängig (Exocarp und Endocarp der Früchte, Blätter). In Zellen der Wurzelspitzen von Maiskeimlingen ist das Enzym in meristematischen Vakuolen lokalisiert. Funktionell ist die saure Carboxypeptidase als lysosomales Enzym, welches am intrazellulären Proteinabbau teilnimmt, anzusprechen.

متن کاملOrgan-specific and hormone-dependent expression of genes for serine carboxypeptidases during development and following germination of rice grains.
Several cDNA clones encoding either serine carboxypeptidases or related proteins of Oryza sativa L. were identified, and the abundance of the corresponding mRNA in immature and germinated grains was examined. The deduced amino acid sequence of each cDNA included key sequences, such as a pentapeptide (G-X-S-X-G/A) that is conserved among many serine carboxypeptidases, and the putative protein pr...
متن کاملFunctional Assessment of an Overexpressed Arabidopsis Purple Acid Phosphatase Gene (Atpap26) in Tobacco Plants
Background: Overexpression of known genes encoding key phosphate (Pi)-metabolizing enzymes, such as acid phosphatases (APases), is presumed to help plants with Pi availability and absorption as they are mostly exposed to suboptimal environmental conditions for this vital element.Objectives: In this study, the overexpression effect of AtPAP26, one of the m...
متن کاملAcid Carboxypeptidases in Grains and Leaves of Wheat, Triticum aestivum L.
Extracts of resting and germinating (3 days at 20 degrees C) wheat (Triticum aestivum L. cv Ruso) grains rapidly hydrolyzed various benzyloxycarbonyldipeptides (Z-dipeptides) at pH 4 to 6. Similar activities were present in extracts of mature flag leaves. Fractionation by chromatography on CM-cellulose and on Sephadex G-200 showed that the activities in germinating grains were due to five acid ...
متن کاملAn expression and bioinformatics analysis of the Arabidopsis serine carboxypeptidase-like gene family.
The Arabidopsis (Arabidopsis thaliana) genome encodes a family of 51 proteins that are homologous to known serine carboxypeptidases. Based on their sequences, these serine carboxypeptidase-like (SCPL) proteins can be divided into several major clades. The first group consists of 21 proteins which, despite the function implied by their annotation, includes two that have been shown to function as...
