On the reduction of aliphatic and aromatic nitro compounds by Clostridia, the role of ferredoxin and its stabilization.
Crude extracts of a variety of Clostridium species reduce aromatic and aliphatic nitro compounds in the presence of hydrogen gas show rates which differ by less than a factor of 3. Expand
On a reversible molybdenum-containing aldehyde oxidoreductase from Clostridium formicoaceticum
Clostridium formicoaceticum grown in the presence of 1 mM molybdate and about 1.5×10-5 mM tungsten (present in the 5 g yeast extract/l of the growth medium) forms two reversible aldehydeExpand
Isotope Effects in Organic Chemistry and Biochemistry
The present article shows the extent to which isotope effects are likely to be encountered in the use of isotope techniques and what problems are studied with primary and secondary isotope effects.Expand
Carboxylic acid reductase: a new tungsten enzyme catalyses the reduction of non-activated carboxylic acids to aldehydes.
The very labile enzyme has been enriched by a factor of about 145 by binding to octyl-Sepharose and further chromatographic separation by red-SepHarose and FPLC using Mono-Q and phenyl-Superose columns. Expand
Stereochemical Studies on Homoterpene Biosynthesis in Higher Plants Mechanistic Phylogenetic and Ecological Aspects
In higher plants, the two homotcrpenes 4,8-dimethylnona-l,3,7-triene (1) and 4,8,12-trimethyltrideca-1,3,7,11-teiracnc (2) originate from nerolidol (3) or geranyllinalool (4) by anoxidative cleavageExpand
Chiral Compounds Synthesized by Biocatalytic Reductions [New Synthetic Methods (51)]
It has been known for many decades that chiral compounds can be obtained by stereospecific biocatalytic reduction. Further significant methodological developments in this field have, however, onlyExpand
Purification, partial characterization and substrate specificity of a squalene cyclase from Bacillus acidocaldarius.
From the thermophilic Bacillus acidocaldarius, a membrane bound cyclase catalysing the formation of 22(29)-hopene and 22-hopanol from squalene was enriched 670-fold to a purity of 95% as judged by gel chromatography. Expand
Purification and Some Properties of a Hitherto‐Unknown Enzyme Reducing the Carbon‐Carbon Double Bond of α,β‐Unsaturated Carboxylate Anions
2-Enoate-reductase, a previously unknown soluble enzyme is present in Clostridium kluyveri and another Clostridium species growing on (E)-2-butenoate. From the latter the reductase was purifiedExpand
Biosynthesis of iridoid monoterpenes in insects - defensive secretions from larvae of leaf beetles (coleoptera, chrysomelidae)
Abstract Larvae of the leaf beetles Phaedon amoraciae, Phaedon cochleariae, Gastrophysa viridula, and Plagiodera versicolora biosynthesize the two iridoids chrysomelidial 1 and/or plagiodial 3 fromExpand
