Rossmann fold

The Rossmann fold is a functional super- secondary structure or a motif in proteins, in which two units of the form beta -alpha -beta -alpha -beta - ie β -sheets connected by α -helices - assemble to dinucleotides such as nicotinamide adenine dinucleotide (NAD ) to bind.

The Rossmann fold is one of the first identified, frequently occurring structural domains. It was named after its discoverer, Michael Rossmann and probably represents an original Dinucleotidbindungsdomäne; they do occurs include on the three dehydrogenases of glycolysis.
