We examined the effects of orally administrated amino acids on myfibrillar proteolysis in food-deprived chicks. Plasma N(tau)-methylhistidine concentration, as an index of myofibrillar proteolysis, was decreased by the administration of Glu, Gly, Ala, Leu, Ile, Ser, Thr, Met, Trp, Asn, Gln, Pro, Lys and Arg but not by Asp, Val, Phe, Tyr or His to chicks. Orally administrated Cys was fatal to ch...
A polypeptide of Mr 4400 was isolated from soybean (Glycine max) seeds by extraction with 60% ethanol followed by ion-exchange and reverse-phase chromatography. The peptide contains an unusually high amount of aspartic acid residues (approximately 25%, and hence is designated as soybean aspartic acid-rich peptide). Its complete primary structure was determined by conventional methods to be the ...
The potential angiotensin-converting enzyme (ACE)-inhibitory and antioxidant activities of peptides in water-soluble extracts, obtained from raw and sterilized ovine and caprine cheeselike systems coagulated with enzymes from the plant Cynara cardunculus, were assessed. Prior to the assay, the 3,000-Da permeate from 45-d-old cheeselike systems was fractionated by tandem chromatographic techniqu...
AIMS To identify a toxin and its producer isolated from woody material in a building where the occupants experienced serious ill health symptoms. METHODS AND RESULTS Hyphal extracts of an indoor fungus, identified as the cycloheximide-tolerant species Acremonium exuviarum, inhibited motility of boar spermatozoa (EC(50) 5 +/- 2 microg of crude solids ml(-1)) and caused cytolysis of murine neur...
The dansyl-conjugated (Dns) peptides Dns-Pro-Gly-Gly-Gln-Gln-Ile-Val and Dns-Ala-Gln-Gln-Ile-Val, patterned on the N-terminal sequence of fibronectin, were synthesized and used for the transglutaminase (protein-glutamine:amine gamma-glutamyltransferase, EC 2.3.2.13)-directed selective blocking of lens proteins that otherwise might participate in donating lysyl side chains in forming N epsilon-(...
The amino acid sequences at the N-terminal ends of the chains of the lens protein, a-crystallin, were studied. Both the main kinds of chain in bovine ix-crystallin (A chains and B chains) have an N-terininal methionine residue, and the amino group is acetylated. Selective purification of the peptides in a tryptic digest of bovirne a-crystallin gave a preparation consisting largely of the N-term...
Manual and automated sequencing of peptides isolated from tryptic, chymotryptic, and Staphylococcus aureus V8 protease digests of the beta chain of histidine decarboxylase from Lactobacillus 30a have established the following sequence for the wild type protein: NH2-Ser-Gly-Leu-Asp-Ala-Lys-Leu-Asn-Lys-Leu-Gly-Val-Asp-Arg-Ile-Ala-Ile-Ser-Pro -Tyr-Lys-Gln-Trp-Thr-Arg-Gly-Tyr-Met-Glu-Pro-Gly-Asn-Il...
We have studied the structure of myosin heavy chain (MHC) in the pectoralis muscle of genetically dystrophic (Connecticut Strain) and White Leghorn chicks. MHC was alkylated with N-ethylmaleimide, purified by Sepharose-4B chromatography, and cleaved with cyanogen bromide. The MHC CNBr peptides were analyzed by one-dimensional and two-dimensional isoelectric focusing/sodium dodecyl sulfate gradi...
Mitochondrial DNA (mtDNA) regions corresponding to two major tRNA gene clusters were amplified and sequenced for the Japanese pit viper, himehabu. In one of these clusters, which in most vertebrates characterized to date contains three tightly connected genes for tRNA(Ile), and tRNA(Gln), and tRNA(Met), a sequence of approximately 1.3 kb was found to be inserted between the genes for tRNA(Ile) ...
NAD+-dependent formate dehydrogenase (FDH) from Candida boidinii was cloned and expressed to a high level in Escherichia coli (20% of soluble E. coli protein). Molecular modelling studies were used to create a three-dimensional model of C. boidinii FDH, based on a known structure of the Pseudomonas sp. 101 enzyme. This model was used for investigating the catalytic mechanism by site-directed mu...
