The crystal structures of 4-methoxybenzoate bound CYP199A2 and CYP199A4: structural changes on substrate binding and the identification of an anion binding site.

Stephen G Bell et al.

Dalton transactions (Cambridge, England : 2003), 41(28), 8703-8714 (2012-06-15)

The crystal structures of the 4-methoxybenzoate bound forms of cytochrome P450 enzymes CYP199A2 and CYP199A4 from the Rhodopseudomonas palustris strains CGA009 and HaA2 have been solved. The structures of these two enzymes, which share 86% sequence identity, are very similar

New 4-methoxybenzoyl derivatives from the ascidian Polycarpa aurata.

M Wessels et al.

Journal of natural products, 64(12), 1556-1558 (2002-01-05)

From the hydrophilic extract of the ascidian Polycarpa aurata three new compounds, N-(4-methoxybenzoyl)-N'-methylguanidine (1), butyl 2-(4-methoxyphenyl)-2-oxoacetate (2), and 2-(4-methoxyphenyl)-N-methyl-2-oxoacetamide (3), together with the known compounds methyl 2-(4-methoxyphenyl)-2-oxoacetate (4) and 4-methoxybenzoic acid were isolated. The structures of all isolates were determined

Reduction of aryl acids by white-rot fungi for the biocatalytic production of aryl aldehydes and alcohols.

A Hage et al.

Applied microbiology and biotechnology, 52(6), 834-838 (2000-01-05)

Ligninolytic basidiomycetes were screened for their ability to reduce aryl acids to the corresponding aldehydes and alcohols. Seven fungal strains converted p-anisic acid in high molar yields to the reduced products. The white-rot fungus Bjerkandera sp. strain BOS55 was one

Two independently regulated cytochromes P-450 in a Rhodococcus rhodochrous strain that degrades 2-ethoxyphenol and 4-methoxybenzoate.

U Karlson et al.

Journal of bacteriology, 175(5), 1467-1474 (1993-03-01)

A red-pigmented coryneform bacterium, identified as Rhodococcus rhodochrous strain 116, that grew on 2-ethoxyphenol and 4-methoxybenzoate as sole carbon and energy sources was isolated. Phylogenetic analysis based on the 16S rDNA sequences indicates that the strain clusters more closely to

Aryl-alcohol oxidase involved in lignin degradation: a mechanistic study based on steady and pre-steady state kinetics and primary and solvent isotope effects with two alcohol substrates.

Patricia Ferreira et al.

The Journal of biological chemistry, 284(37), 24840-24847 (2009-07-04)

Aryl-alcohol oxidase (AAO) is a FAD-containing enzyme in the GMC (glucose-methanol-choline oxidase) family of oxidoreductases. AAO participates in fungal degradation of lignin, a process of high ecological and biotechnological relevance, by providing the hydrogen peroxide required by ligninolytic peroxidases. In
