NADP+ binding

Definition

Target type: molecularfunction

Binding to the oxidized form, NADP+, of nicotinamide-adenine dinucleotide phosphate, a coenzyme involved in many redox and biosynthetic reactions. [GOC:mah]

NADP+ binding is a molecular function that involves the interaction of a protein or other molecule with the coenzyme NADP+. NADP+ is a crucial electron carrier in various metabolic pathways, including photosynthesis and fatty acid biosynthesis. It acts as an electron acceptor, becoming reduced to NADPH when it gains electrons. This reduction is essential for providing reducing power to drive anabolic reactions. NADP+ binding proteins often possess specific domains or motifs that facilitate the interaction with the coenzyme. These binding sites are typically characterized by their structural features and the presence of key amino acid residues involved in hydrogen bonding and electrostatic interactions with NADP+. The binding of NADP+ to its respective protein can regulate the activity of the enzyme by inducing conformational changes, altering substrate affinity, or promoting the assembly of multi-protein complexes. This interaction is crucial for maintaining cellular redox balance, facilitating energy production, and supporting essential biosynthetic processes.'
