The association of this molecule with a protein found in egg whites has a dissociation constant of ten to the minus fourteen molar.
A complex of HPDP and this molecule is used to detect protein S-nitroÂ·sylÂ·ation in its namesake "switch" assay. In Hi-C, 送ve-prime overhangs are labeled with a fourteen-dÂ·CÂ·TÂ·P nucleotide analog containing this molecule. SELEX ("sell"-ex) uses primers attached to this molecule to immobilize the resulting nucleic acids. This molecule is used as a coÂ·factor by an enzyme that converts acetyl-CoA to malÂ·onÂ·yl-CoA in the 送rst step of fatty acid synthesis, and an enzyme that converts pyruvate to oxÂ·aloÂ·acetate in the 送rst step of glucoÂ·neoÂ·genesis. The structure of this cofactor is distinguished by a ureido (yur-"eye"-doh) ring fused to a tetraÂ·hydroÂ·thioÂ·phene ring and it is utilized exclusively by carbÂ·oxylÂ·ase enzymes. The association of this molecule with a protein found in egg whites has a dissociation constant of ten to the minus fourteen molar. For 10 points, name this B vitamin that binds extremely tightly to aviÂ·din and streptÂ·aviÂ·din.
