Biotin, a universal and essential cofactor: Synthesis, ligation and regulation.
Biotin is a covalently attached enzyme cofactor required for intermediary metabolism in all three domains of life. Several important human pathogens (e.g. Mycobacterium tuberculosis) require biotin synthesis for pathogenesis.

Biotin's Lessons in Drug Design.
At the heart of drug design is the discovery of molecules that bind with high affinity to their drug targets. Biotin forms the strongest known noncovalent ligand-protein interactions with avidin and streptavidin, achieving femtomolar and picomolar ...

Biotin, or vitamin B7, is essential for metabolic reactions. It must be obtained from external sources such as food and biotin/vitamin supplements because it is not biosynthesized by mammals.

Streptavidin/biotin: Tethering geometry defines unbinding mechanics
Single-molecule force spectroscopy reveals how the mechanical stability of a widely used biomolecular complex varies fourfold. Macromolecules tend to respond to applied forces in many different ways. Chemistry at high shear forces can be intriguing, with

Background The amino acid-producing Gram-positive Corynebacterium glutamicum is auxotrophic for biotin although biotin ring assembly starting from the precursor pimeloyl-CoA is still functional.

Impedimetric aptasensors without signal amplification exhibit poor sensitivity for the detection of small molecule contaminants. In this work, biotinylated nanoparticles of biotin-FNPs were readily prepared by the self-assembly of biotin-phenylalanine ...

AACC Guidance Document on Biotin Interference in Laboratory Tests.
BACKGROUND Laboratory tests that use streptavidin-biotin binding mechanisms have the potential to be affected by high circulating biotin concentrations, which would produce positive and negative interference in biotinylated competitive and noncompetitive

Mechanisms of biotin-regulated gene expression in microbes
Biotin is an essential micronutrient that acts as a co-factor for biotin-dependent metabolic enzymes. In bacteria, the supply of biotin can be achieved by de novo synthesis or import from exogenous sources.
