This study examined the microbial transformation of carbazole (CZ) by an isolated bacterium that can use CZ as a sole carbon and nitrogen source. The strain identified as Pseudomonas stutzeri produced a large amount of anthranilic acid (AA) from CZ in the medium containing a nonionic surfactant. In dialysis culture using ion-exchange resin, 7.9 g/liter (58mm) of AA was accumulated from 15g/lite...
In the title compound, C(14)H(15)NO(2), the hydrogenated six-membered ring of the carbazole unit adopts a half-chair conformation and the dioxolane ring points to one side of the carbazole plane. Neighbouring mol-ecules form edge-to-face inter-actions in which the NH group is directed towards an adjacent carbazole unit, with a shortest H⋯C contact of 2.72 Å. These inter-actions arrange the mol-...
In the title compound, C(18)H(21)NO(4), the hydrogenated six-membered ring of the carbazole unit adopts a half-chair conformation. The dioxolane ring and ethyl-acetate substituent point to opposite sides of the carbazole plane. The ethyl-acetate substituent adopts an essentially fully extended conformation, and its mean plane forms a dihedral angle of 83.8 (1)° with respect to the carbazole mea...
Carbazole 1,9a-dioxygenase (CARDO), a Rieske nonheme iron oxygenase (RO), is a three-component system composed of a terminal oxygenase (Oxy), ferredoxin, and a ferredoxin reductase. Oxy has angular dioxygenation activity against carbazole. Previously, site-directed mutagenesis of the Oxy-encoding gene from Janthinobacterium sp. strain J3 generated the I262V, F275W, Q282N, and Q282Y Oxy derivati...
The mol-ecule of the title compound, C(31)H(29)N(3), contains a hexyl chain, a coordination unit (benzimidazole) and a functional group (carbazole). The benzimidazole ring is not coplanar with either the phenyl ring or the carbazole system, making dihedral angles of 43.26 (3) and 39.03 (2)°, respectively. The dihedral angle between the phenyl ring and the carbazole system is 24.42 (3)°. The hex...
The carbazomycins were isolated from Streptoverticillium ehimense H 1051 MY10 as the first antibiotics containing a carbazole nucleus and they mainly inhibit the growth of phytopathogenic fungi3'40. The complex consists of eight components; carbazomycins B (1), A, C, D, E, F, G and H, and their structures were elucidated by spectroscopic and chemical means together with X-ray crystallographic a...
