Abstract Cell-free extracts from Pseudomonas cepacia and Nocardia sp. when supplied with NADPH accumulated undecyl acetate from 2-tridecanone in the presence of an esterase inhibitor, tetraethyl pyrophosphate. Mass spectra of undecyl acetate formed in an 16O2-atmosphere exhibited characteristic oxygencontaining ions of m/e 61, 73, and 116. In experiments with 18O2, these ions appeared at m/e 63, 75, and 118. Absence of a significant peak at m/e 45 in the 18O-containing ester established that… Expand
Bacterial Degradation of Ring-Chlorinated Acetophenones
Two strains, Alcaligenes sp. strain ACA and Pseudomonas fluorescens ACB, isolated from acetophenone and 4′-hydroxyacetophenone enrichments, respectively, cometabolize a range of chlorinatedExpand
The purification and properties of cyclohexanone oxygenase from Nocardia globerula CL1 and Acinetobacter NCIB 9871.
1. Cyclohexanone oxygenases from Norcardia globerula CL1 and Acinetobacter NCIB 9871 have been purified 12-fold and 35-fold respectively and each gives a single symmetrical sedimentation peak in theExpand
Production of Wax Esters during Aerobic Growth of Marine Bacteria on Isoprenoid Compounds
The production of isoprenoid wax esters during the aerobic degradation of 6,10,14-trimethylpentadecan-2-one and phytol by four bacteria isolated from the marine environment is described and it seems likely that, under some conditions, bacterial esterification can enhance the preservation potential of labile compounds such asphytol.

The aerobic bacterial metabolism of phytol in seawater: Temperature dependence of an abiotic intermediate step and its consequences
Abstract A non-negligible production of 6,10,14-trimethylpentadecan-2-one has been often observed during aerobic phytol incubations with bacteria. In this work involving a marine Acinetobacter , aExpand
Incorporation of 18O into long-chain, secondary alcohols derived from ester mycolic acids in Mycobacterium phlei
Abstract 18 O from an 18 O 2 atmosphere was actively incorporated into long-chain, secondary alcohols, such as 2-octadecanol, 2-eicosanol and 2-docosanol, which are derived from ester mycolic acids,Expand
Oxidation of n-alkanes by citric acid producingCandida spp.
SummaryMicrobial oxidation and assimilation of n-tetradecane by two citric acid-producingCandida sp. (a wild typeCandida sp. KSH 21 and mutant from this strain No. 337) were studied.A monoterminalExpand
The metabolism of trans-cyclohexan-1,2-diol by an Acinetobacter species.
The failure of Acinetobacter TD63 to grow with cyclo hexanol, cyclohexanone or 1-oxa-2-oxocycloheptane is due not to this organism possessing a distinctive metabolic sequence but to a narrow inducer specificity coupled with an inability to form a lactone hydrolase enabling it to cleave the stable 1- oxa- 2-oxohexanoate to adipate.

Aerobic and anaerobic metabolism of 6,10,14-trimethylpentadecan-2-one by a denitrifying bacterium isolated from marine sediments
This report describes the metabolism of 6,10,14-trimethylpentadecan-2-one by a denitrifying bacterium isolated from marine sediments and proposes different pathways to explain the formation of such isoprenoid compounds. Expand
A fatty acid alpha-ketol, a product of the plant lipoxygenase pathway, is oxidized to 3(Z)-dodecendioic acid by a bacterial monooxygenase.
These findings offer both a physiological role for alpha-ketol fatty acids in plant lipid hydroperoxide metabolism and new insights into an alternative biosynthetic pathway leading to traumatic acid (2(E)-dodecendioic acid). Expand
Oxygen Activation by Flavins and Pterins
As discussed in other chapters in this volume, the high reduction potential of O2 makes it thermodynamically an excellent oxidizing agent for most biochemicals. However, the activation energy forExpand


Oxidative Degradation of Methyl Ketones II. Chemical Pathway for Degradation of 2-Tridecanone by Pseudomonas multivorans and Pseudomonas aeruginosa
Discovery of undecyl acetate confirms the earlier contention that the primary attack on methyl ketones by bacteria can be by subterminal oxidation and accounts for the conversion of 2-tridecanone to provide carbon and energy for growth. Expand
Specificity and Induction of Undecyl Acetate Esterase from Pseudomonas cepacia Grown on 2-Tridecanone
Induction of undecyl acetate esterase during oxidation of 2-tridecanone supports the view that undecylon acetate is an intermediate in the degradation of the methyl ketone. Expand
Purification and Properties of Undecyl Acetate Esterase from Pseudomonas cepacia Grown on 2-Tridecanone
Molecular sieve polyacrylamide gel electrophoresis indicated that the two esterases had the same molecular weight but different charge, which is indicative of isoenzymes. Expand
Bacterial Oxidation of 2-Tridecanone to 1-Undecanol
A pathway for utilization of 2-tridecanone was proposed that is consistent with, but not confirmed by, the data presented, and it is established that some unique mechanism that involves subterminal oxidation must exist to degrade 2-Tride canone. Expand

Abstract Two enzymes are responsible for the cleavage of pregnane side chains. A steroid-inducible oxygenase, in the presence of reduced nicotinamide adenine trinucleotide and molecular oxygen,Expand
An enzyme system for aliphatic methyl ketone oxidation.
