Aqueous dissociation constants of bile pigments and sparingly soluble carboxylic acids by 13C NMR in aqueous dimethyl sulfoxide: effects of hydrogen bonding

Journal of Lipid Research, 1997
pKas for the acid dissociation of the carboxyl groups of bilirubin in water have been reported recently to be 8.1-8.4, or higher. These high values were attributed to intramolecular hydrogen bonding.

Heme-binding enables allosteric modulation in an ancient TIM-barrel glycosidase

Nature Communications, 2021
Family 1 glycosidases (GH1) are present in the three domains of life and share classical TIM-barrel fold. Structural and biochemical analyses of a resurrected ancestral GH1 enzyme reveal heme binding, not known in its modern descendants.
