Purification and partial characterization of aminopeptidase from barley (Hordeum vulgare L.) seeds.

2013

Aminopeptidases (EC 3.4.11) are proteolytic enzymes, which hydrolyze one amino acid from N-terminus of peptidic substrates. Inhibitors of plant aminopeptidases can find an application in agriculture as herbicides. Isolation and partial characterization of aminopeptidase from barley (Hordeum vulgare L.) seeds has been described. The enzyme was purified to molecular homogeneity using a six-step purification procedure (precipitation with (NH4)2SO4, followed by chromatography on Sephadex G-25, DEAE-Sepharose, Sephacryl HR 300, Macro-Prep Q and Phenyl-Sepharose HP columns). The enzyme was purified 365-fold with recovery above 18%. The molecular weight of the purified enzyme was determined by SDS…

Caracterización y germinación de semillas de Genista umbellata (L'Her.) Poir. (LEGUMINOSAE)

2016

Los territorios áridos y semiáridos del SE de la Península ibérica, nos ofrecen algunas especies con un gran atractivo de carácter ornamental. La especie analizada en esta ficha es un buen ejemplo de este hecho. Destaca por su profusa floración primaveral, con flores de un intenso color amarillo e inflorescencias en umbela. Este trabajo se ha cofinanciado por la Generalitat Valenciana (Consellería de Agricultura, Medio Ambiente, Cambio Climático y Desarrollo Rural, Servicio de Biodiversidad) y la Universitat de València.
