Isolation and in silico characterization of full-length cinnamyl alcohol dehydrogenase gene involved lignin biosynthesis Neolamarckia cadambaBoon-Ling Tchin, Wei-Seng Ho, Shek-Ling Pang
lignin is one of the major characteristics of plant secondary cell wall that provides structural rigidity for the cells and tissues and hydrophobicity to tracheary elements. internode tissues of aeluropus littoralis as a halophyte grass were sampled at different developmental stages (from the first to the fifth internodes ) and under different nacl concentrations. the influences of nacl and int...
Cinnamyl alcohol dehydrogenases (CAD; 1.1.1.195) catalyse the reversible conversion of p-hydroxycinnamaldehydes to their corresponding alcohols, leading to the biosynthesis of lignin in plants. Outside of plants their role is less defined. The gene for cinnamyl alcohol dehydrogenase from Helicobacter pylori (HpCAD) was cloned in Escherichia coli and the recombinant enzyme characterized for subs...
Using horse liver alcohol dehydrogenase, stereospecifically tritiated (R)and (S)-(y-3H)-coniferyl alcohol was synthesized. Using both of these substrates it was demonstrated that cinnamyl alcohol dehydrogenase from lignifying Forsythia tissue specifically removes the pro-R-hydrogen atom of coniferyl alcohol in the oxidation to the aldehyde. This also means that in the reverse reaction the A-hyd...
A series of transgenic poplars down-regulated for cinnamyl alcohol dehydrogenase (CAD) was analyzed by thioacidolysis. Among the lignin-derived monomers, the indene compounds that were recently shown to originate from sinapaldehyde incorporated into lignins through 8-O-4-cross-coupling, were found to increase as a function of CAD deficiency level. While these syringyl markers were recovered in ...
Phylogeny and structure of the cinnamyl alcohol dehydrogenase gene family in Brachypodium distachyon
Cinnamyl alcohol dehydrogenase (CAD) catalyses the final step of the monolignol biosynthesis, the conversion of cinnamyl aldehydes to alcohols, using NADPH as a cofactor. Seven members of the CAD gene family were identified in the genome of Brachypodium distachyon and five of these were isolated and cloned from genomic DNA. Semi-quantitative reverse-transcription PCR revealed differential expre...
The enzyme activity of alcohol dehydrogenases 4W6Z and 1MG5 demonstrated good agreement with the calculated a-carbon atomic partial charges of the substrates. The correlation coefficients were found to be more than 0.8 (n = 9) for both the oxidation and reduction reactions. The stereo structure of cinnamylalcohol dehydrogenase (ELI3-2) was constructed modification in 1PIW (cinnamyl alcohol dehy...
Evidence for the molecular basis of a null allele of cinnamyl alcohol dehydrogenase (CAD) has been discovered in the loblolly pine (Pinus taeda L.) clone 7-56. The mutation is a two-base pair adenosine insertion located in exon 5 that causes a frame-shift which is predicted to result in premature termination of the protein. For routine detection of the mutation, a diagnostic assay was developed...
