WebWRINKLED1 (WRI1) is a transcriptional activator that binds to a conserved sequence (designated as AW box) boxes in the promoters of many genes from central metabolism and fatty acid (FA) synthesis, resulting in their transcription. BIOTIN ATTACHMENT DOMAIN-CONTAINING (BADC) proteins lack a biotin-attachment domain and are therefore … WebJan 11, 2024 · INTRODUCTION. Biotin (also called vitamin H or B7) is an essential cofactor of biotin-dependent enzymes including carboxylases, decarboxylases and transcarboxylases, all of which participate in various aspects of intermediary metabolism, including gluconeogenesis, fatty acid synthesis and amino acid metabolism (Walsh …

Biotin in metabolism, gene expression, and human disease
Biotin is a coenzyme for five carboxylase enzymes, which are involved in the catabolism of amino acids and fatty acids, synthesis of fatty acids, and gluconeogenesis. [3] [4] Biotinylation of histone proteins in nuclear chromatin plays a role in chromatin stability and gene expression. See more Biotin (or vitamin B7) is one of the B vitamins. It is involved in a wide range of metabolic processes, both in humans and in other organisms, primarily related to the utilization of fats, carbohydrates, and amino acids. The … See more Biotin is classified as a heterocyclic compound, with a sulfur-containing ring fused ureido and tetrahydrothiophene group. A C5-carboxylic acid side chain is appended to one of the rings.
