Metabolic-Engineering Approach to Enhance Vanillin and Phenolic Compounds in Ocimum Sanctum (CIM-Angana) via VpVAN Overexpression.

Transgenic Ocimum sanctum plants were engineered to produce vanillin by overexpressing the VpVAN gene using Agrobacterium-mediated transformation. Positive transformants developed shoots within 4-5 weeks and were transferred to a root induction medium and four independent transformants with no observed adverse effects were kept for anlysis. Quantitative RT-PCR indicated significantly higher VpVAN expression in transgenic lines AG_3 and AG_1, impacting the phenylpropanoid pathway and phenolic compound accumulation.

Metabolic engineering of hairy root cultures in for enhanced production of vanillin, 4-hydroxybenzoic acid, and vanillyl alcohol.

The flavor of vanilla is a complex blend of compounds, with vanillin as the most prominent, along with vanillyl alcohol and 4-hydroxybenzoic acid. Natural vanillin extracted from vanilla beans is expensive, so researchers use heterologous synthesis to produce nature-identical vanillin in plant hosts. Consequently, alternative traditional farming and gathering methods are required to bridge the significant disparity between supply and demand.

Effect of Differential Backbone Di-substitution of Gamma Amino Acid Residues on the Conformation and Assembly of their Fmoc Derivatives in Solid and Solution States.

We studied the effect of variable backbone dimethyl-substitution of γ amino acid residues (γ , γ and γ ) on the conformation and assembly, in crystals and solution of their Fmoc derivatives. The crystal structure of γ and γ derivatives showed distinct conformations (open/close for γ /γ ) that differed in torsion angles, hydrogen-bonding and most importantly the π-π Fmoc-stacking interactions (relatively favourable for γ -close). Fmoc derivatives existed in an equilibrium between major-monomeric (low energy, non-hydrogen bonded) and minor-dimeric (high energy, hydrogen bonded) populations in solution.
