THE HISTOCHEMICAL DEMONSTRATION OF LEUCINE AMINOPEPTIDASE
, 1957 1. A method is described for the histochemical localization of leucine aminopeptidase in fresh frozen and paraffin embedded tissues. 2. Evidence is offered which supports the idea that the substrate l-leucyl-β-naphthylamide is hydrolyzed by leucine ...

Root hairs and protein addition to soil promote leucine aminopeptidase activity of Hordeum vulgare L [PDF]
, 2021 Protein typically represents the largest input of organic nitrogen (N) into soil. Proteases subsequently make this protein available for use by both plants and microorganisms, however, the factors that regulate protein breakdown in the rhizosphere remain

Structure and Function of a Multi‐Megadalton Virus‐Like Proteolytic Dodecahedron
Angewandte Chemie International Edition, EarlyView.Zuzalysin, a virulence metallopeptidase of the periodontal pathogen Porphyromonas gingivalis, is secreted as a latent, flexible ≈95‐kDa monomer. Calcium triggers cysteine‐switch activation and hierarchical assembly into pentamers, bipentamers, tripentamers, and a ≈5.6‐MDa, ≈355‐Å dodecahedron. Structures at 1.8–3.6 Å reveal a virus‐sized catalytic cage

Proteolytic inactivation of leucine aminopeptidase in extracts from bean seeds: effect of solutes [PDF]
, 1987 Cotyledons from dwarf beans (Phaseolus vulgaris.L., var. "Saxa") were extracted at two different stages of germination. Extract from ungerminated seeds (low endopeptidase activity) contained high leucine aminopeptidase activity, which was stable for ...

A Quantitative Chromatographic Method for the Determination of Leucine Aminopeptidase Activity [PDF]
, 1967 A micro method for the determination of leucine aminopeptidase activity was developed. Leucinamide was us ed as substrate. The liberated leucin e was quantitative ly determined using paper chromatography a nd reflectanc e-densitometrical scanning of ...
