Biotin, a universal and essential cofactor: Synthesis, ligation and regulation.

open access: yesFEMS Microbiology Reviews, 2021
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.

open access: yesJournal of Medicinal Chemistry, 2021
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 ...

Biotinylated Quinone as a Chemiluminescence Sensor for Biotin-Avidin Interaction and Biotin Detection Application

open access: yesSensors, 2023
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

open access: yesScience Advances, 2020
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

Characterization of the biotin uptake system encoded by the biotin-inducible bioYMN operon of Corynebacterium glutamicum

open access: yesBMC Microbiology, 2012
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.

Competitive impedimetric aptasensors for detection of small molecule pollutants by the signal amplification of self-assembled biotin-phenylalanine nanoparticle networks

open access: yesElectrochemistry Communications, 2020
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 ...

A promiscuous biotin ligase fusion protein identifies proximal and interacting proteins in mammalian cells

open access: yesJournal of Cell Biology, 2012
Proximity-dependent biotin identification (BioID) is a new approach making use of biotin ligase fusion proteins for the identification of both interacting and neighboring proteins in their native cellular environment.

AACC Guidance Document on Biotin Interference in Laboratory Tests.

open access: yesThe Journal of Applied Laboratory Medicine, 2020
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

open access: yesSynthetic and Systems Biotechnology, 2016
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.
