Degradation of the thiocarbamate herbicide EPTC (S-ethyl dipropylcarbamothioate) and biosafening by Rhodococcus sp. strain NI86/21 involve an inducible cytochrome P-450 system and aldehyde
It was demonstrated that the aldehyde dehydrogenase gene is widespread in the Rhodococcus genus, but the components of the cytochrome P-450 system are unique to Rhoditis sp. Expand
A single cytochrome P-450 system is involved in degradation of the herbicides EPTC (S-ethyl dipropylthiocarbamate) and atrazine by Rhodococcus sp. strain NI86/21
During atrazine degradation by Rhodococcus sp. strain N186/21, N-dealkylated metabolites and an hydroxyisopropyl derivative are produced. The cytochrome P-450 system that is involved in degradationExpand
Biohydrogenation of sterols by Eubacterium ATCC 21,408--Nova species.
Eubacterium 21,408, a strictly anaerobic bacterium, was isolated from rat cecal contents by its requirements for a Δ5-3β-hydroxy steroid and reduced the 5,6-double bond of cholesterol, campesterol, β-sitosterol and stigmasterol, exclusively yielding the corresponding 5β-saturated derivatives.

Identification of steviol glucuronide in human urine.
This is the first report on the unambiguous identification of steviol glucuronide in human urine by MS, NMR, IR, and UV spectroscopy. Expand
Biosynthesis of the diterpenoid steviol, an ent-kaurene derivative from Stevia rebaudiana Bertoni, via the methylerythritol phosphate pathway
Abstract As shown from [1- 13 C]glucose incorporation, steviol, the diterpene aglycone moiety of stevioside, is synthesized in Stevia rebaudiana Bertoni via the mevalonate-independentExpand
Cloning and heterologous expression of early genes in gibberellin and steviol biosynthesis via the methylerythritol phosphate pathway in Stevia rebaudiana
The ent-kaurene skeleton of chloroplast diterpene glycosides, which are produced in large quantities in the leaves of Stevia rebaudiana Bertoni, is formed via the recently discovered 2-C-methyl-D-erythritol 4-phosphate pathway and it is demonstrated through heterologous expression in Escherichia coli that the cloned cDNAs encode functional proteins.

Study of the carbonyl products of terpene/OH radical reactions: detection of the 2,4-DNPH derivatives by HPLC-MS
The oxidation of the terpenes α- and β-pinene, limonene and Δ3-carene by hydroxyl radicals has been investigated in a fast-flow reactor coupled to a liquid nitrogen trap for collecting the carbonylExpand
Recent advances in the separation and analysis of diazo-positive bile pigments.
Mass spectral evidence for N-glycans with branching on fucose in a molluscan hemocyanin.
The tetrasaccharide unit contains a central fucose moiety substituted with 3-O-methylgalactose and N-acetylgalactosamine, and linked to GlcNAc at the reducing end represents a novel N-glycan motif and is likely to be immunogenic. Expand
