importance of the isovalerate carboxylation pathway of leucine biosynthesis in the rumen.certain anaerobic ruminal bacteria synthesize the leucine carbon skeleton by use of a pathway different from that described in other microorganisms. these organisms carboxylate the intact carbon skeleton of isovalerate, synthesizing leucine-2-c(14) from isovalerate-1-c(14). strains of bacteroides ruminicola and peptostreptococcus elsdenii were like ruminococcus flavefaciens in that they incorporated appreciable amounts of c(14) from isovalerate-1-c(14) into cellular protein and in that the only ...19665970468

tracer studies on the biosynthesis of amino acids from lactate by peptostreptococcus elsdenii.peptostreptococcus elsdenii, a strict anaerobe from the rumen, was grown on a medium containing yeast extract and [1-(14)c]- or [2-(14)c]-lactate. radioisotope from lactate was found in all cell fractions, but mainly in the protein. the label in the protein fraction was largely confined to a few amino acids: alanine, serine, aspartic acid, glutamic acid and diaminopimelic acid. the alanine, serine, aspartic acid and glutamic acid were separated, purified and degraded to establish the distributio ...19676069834

pectin-fermenting bacteria isolated from the bovine rumen.thirty-two strains of pectin-fermenting rumen bacteria were isolated from bovine rumen contents in a rumen fluid medium which contained pectin as the only added energy source. based on differences in morphology and the gram stain, 10 of these strains were selected for characterization. two strains were identified as lachnospira multiparus, four strains were identified as butyrivbrio fibrisolvens, and three strains were identified as bacteroides ruminicola. characteristics of the remaining strain ...19695802604
isoleucine biosynthesis from 2-methylbutyric acid by anaerobic bacteria from the rumen.microorganisms in ruminal ingesta and pure cultures of anaerobic ruminal bacteria of different physiological and morphological groups incorporated (14)c from labeled 2-methylbutyrate during growth. the radioactivity was incorporated mainly into lipid and protein. isoleucine was the only labeled amino acid found in acid hydrolysates of protein from either pure or mixed cultures. radioactivity in isoleucine synthesized from 2-methylbutyrate-1-(14)c was entirely in carbon-2. thus, the carboxylation ...19695813342

the purification and properties of butyryl-coenzyme a dehydrogenase from peptostreptococcus elsdenii.butyryl-coa dehydrogenase prepared by a simple procedure from peptostreptococcus elsdenii has a molecular weight of approx. 150000. the enzyme has fad as its prosthetic group. the amino acid analysis is reported. this enzyme, like most of the corresponding mammalian ones, is green. the absorption band at 710nm can be abolished irreversibly by dithionite reduction and air reoxidation; it can be abolished reversibly by phenylmercuric acetate or potassium bromide. the enzyme as isolated appears to ...19715145910
green butyryl-coenzyme a dehydrogenase. an enzyme-acyl-coenzyme a complex.1. butyryl-coa dehydrogenase from peptostreptococcus elsdenii forms very tightly bound complexes with various acyl-coa compounds. spectra in some cases merely show resolution of the 450nm band, but those with acetoacetyl-, pent-2-enoyl- and 4-methylpent-2-enoyl-coa show long-wavelength bands similar to the 710nm band of native enzyme. these complexes are formed instantaneously by the yellow form of the enzyme and much more slowly by the green form. 2. an acid extract of the green enzyme reconver ...19715145911

dependence of the proton magnetic resonance spectra on the oxidation state of flavodoxin from clostridium mp and from peptostreptococcus elsdenii.the broadening of protein nuclear magnetic resonances in the spectra of the semiquinone forms of flavodoxins derived from clostridium mp and peptostreptococcus elsdenii relative to the resonances in the oxidized and reduced forms is highly selective. spectra from both species of flavodoxin indicate that conformational differences between the oxidized and fully reduced states are minor and, consequently, the broadening in the semiquinone form is ascribed to the paramagnetic effect of the flavin f ...19734519623
