Use of a distant reporter group as evidence for a conformational change in a sensory receptor [PDF]
A highly sensitive method for demonstrating ligand-induced conformational changes in protein molecules in solution is described. The method utilizes an environmentally sensitive reporter group that is known to be distant from the active site.

Aminopeptidase C of Aspergillus niger is a Novel Phenylalanine Aminopeptidase [PDF]
A novel enzyme with a specific phenylalanine aminopeptidase activity (ApsC) from Aspergillus niger (CBS 120.49) has been characterized. The derived amino acid sequence is not similar to any previously characterized aminopeptidase sequence but does share ...

Incorporation in vitro of labeled amino acids into proteins of rabbit reticuloytes [PDF]
Continuing our work on the incorporation of labeled amino acids into proteins (1), we have begun a study of the incorporation in vitro of C14-labeled glycine, L-histidine, L-leucine, and L-lysine into the proteins of rabbit reticulocytes.

DmCatD, a cathepsin D-like peptidase of the hematophagous insect Dipetalogaster maxima (Hemiptera: Reduviidae): Purification, bioinformatic analyses and the significance of its interaction with lipophorin in the internalization by developing oocytes [PDF]
DmCatD, a cathepsin D-like peptidase of the hematophagous insect Dipetalogaster maxima, is synthesized by the fat body and the ovary and functions as yolk protein precursor. Functionally, DmCatD is involved in vitellin proteolysis.

In Vitro Stability and Inactivation of Peptide Hydrolases Extracted from Phaseolus vulgaris L [PDF]
Endopeptidase activity against azocasein had a higher temperature optimum (50°C) in leaf extracts than in cotyledon extracts (37°C). The temperature optima for aminopeptidase (46°C) and for carboxypeptidase (53°C) were similar in leaf and cotyledon ...

Substrate Selectivity and Molecular Adaptation in the Outer Membrane Proteases of Yersinia pestis and Salmonella enterica [PDF]
Proteolysis is important in bacterial pathogenesis and colonization of animal and plant hosts. In this work I have investigated the functions of the bacterial outer membrane proteases, omptins, of Yersinia pestis and Salmonella enterica. Y.

Enzymatic semisynthesis of insulin specifically labelled with tritium at position B-30 [PDF]
We have synthesized porcine insulin labelled with tritium at position B-30 using enzyme-catalysed formation of a peptide bond. The resulting insulin derivative has the label in the expected position and is biologically active.

Pseudomurein endoisopeptidases PeiW and PeiP, two moderately related members of a novel family of proteases produced in Methanothermobacter strains [PDF]
Sequence comparison of pseudomurein endoisopeptidases PeiW encoded by the defective prophage ΨM100 of Methanothermobacter wolfeii, and PeiP encoded by phage ΨM2 of Methanothermobacter marburgensis, revealed that the two enzymes share only limited ...
