Molecular characterization of genes of Pseudomonas sp. strain HR199 involved in bioconversion of vanillin to protocatechuate.
Priefert H., Rabenhorst J., Steinbuechel A.
The gene loci vdh, vanA, and vanB, which are involved in the bioconversion of vanillin to protocatechuate by Pseudomonas sp. strain HR199 (DSM 7063), were identified as the structural genes of a novel vanillin dehydrogenase (vdh) and the two subunits of a vanillate demethylase (vanA and vanB), res ... >> More
The gene loci vdh, vanA, and vanB, which are involved in the bioconversion of vanillin to protocatechuate by Pseudomonas sp. strain HR199 (DSM 7063), were identified as the structural genes of a novel vanillin dehydrogenase (vdh) and the two subunits of a vanillate demethylase (vanA and vanB), respectively. These genes were localized on an EcoRI fragment (E230), which was cloned from a Pseudomonas sp. strain HR199 genomic library in the cosmid pVK100. The vdh gene was identified on a subfragment (HE35) of E230, and the vanA and vanB genes were localized on a different subfragment (H110) of E230. The nucleotide sequences of fragment HE35 and part of fragment H110 were determined, revealing open reading frames of 1062, 951, and 1446 bp, representing vanA, vanB, and vdh, respectively. The vdh gene was organized in one operon together with a fourth open reading frame (ORF2), of 735 bp, which was located upstream of vdh. The deduced amino acid sequences of vanA and vanB exhibited 78.8 and 62.1% amino acid identity, respectively, to the corresponding gene products from Pseudomonas sp. strain ATCC 19151 (F. Brunel and J. Davison, J. Bacteriol. 170:4924-4930, 1988). The deduced amino acid sequence of the vdh gene exhibited up to 35.3% amino acid identity to aldehyde dehydrogenases from different sources. The deduced amino acid sequence of ORF2 exhibited up to 28.4% amino acid identity to those of enoyl coenzyme A hydratases. Escherichia coli strains harboring fragment E230 cloned in pBluescript SK-converted vanillin to protocatechuate via vanillate, indicating the functional expression of vdh, vanA, and vanB in E. coli. High expression of vdh in E. coli was achieved with HE35 cloned in pBluescript SK-. The resulting recombinant strains converted vanillin to vanillate at a rate of up to 0.3 micromol per min per ml of culture. Transfer of vanA, vanB, and vdh to Alcaligenes eutrophus and to different Pseudomonas strains, which were unable to utilize vanillin or vanillate as carbon sources, respectively, conferred the ability to grow on these substrates to these bacteria. << Less

Vanillin dehydrogenase (VDH) is a crucial enzyme involved in the degradation of lignin-derived aromatic compounds. Herein, the VDH from Corynebacterium glutamicum was characterized. The relative molecular mass (Mr) determined by SDS-PAGE was ~51 kDa, whereas the apparent native Mr values revealed by gel filtration chromatography were 49.5, 92.3, 159.0 and 199.2 kDa, indicating the presence of dimeric, trimeric and tetrameric forms. Moreover, the enzyme showed its highest level of activity toward vanillin at pH 7.0 and 30°C, and interestingly, it could utilize NAD(+) and NADP(+) as coenzymes with similar efficiency and showed no obvious difference toward NAD(+) and NADP(+). In addition to vanillin, this enzyme exhibited catalytic activity toward a broad range of substrates, including p-hydroxybenzaldehyde, 3,4-dihydroxybenzaldehyde, o-phthaldialdehyde, cinnamaldehyde, syringaldehyde and benzaldehyde. Conserved catalytic residues or putative cofactor interactive sites were identified based on sequence alignment and comparison with previous studies, and the function of selected residues were verified by site-directed mutagenesis analysis. Finally, the vdh deletion mutant partially lost its ability to grow on vanillin, indicating the presence of alternative VDH(s) in Corynebacterium glutamicum. Taken together, this study contributes to understanding the VDH diversity from bacteria and the aromatic metabolism pathways in C. glutamicum. << Less

Whole-cell bioconversion of vanillin to vanillic acid by Streptomyces viridosporus.
Pometto A.L., Crawford D.L.
A two-step batch fermentation-bioconversion of vanillin (4-hydroxy-3-methoxybenzaldehyde) to vanillic acid (4-hydroxy-3-methoxybenzoic acid) was developed, utilizing whole cells of Streptomyces viridosporus T7A.

A two-step batch fermentation-bioconversion of vanillin (4-hydroxy-3-methoxybenzaldehyde) to vanillic acid (4-hydroxy-3-methoxybenzoic acid) was developed, utilizing whole cells of Streptomyces viridosporus T7A. In the first step, cells were grown in a yeast extract-vanillin medium under conditions where cells produced an aromatic aldehyde oxidase. In the second step, vanillin was incubated with the active cells and was quantitatively oxidized to vanillic acid which accumulated in the growth medium. Vanillic acid was readily recovered from the spent medium by a combination of acid precipitation and ether extraction at greater than or equal to 96% molar yield and upon recrystallization from glacial acetic acid was obtained in greater than or equal to 99% purity. << Less
