The sentence "Walker A motif is best known for its presence in nucleotide-binding proteins, but is also found in a variety of proteins with widely varying functions, including the alpha and beta subunits of ATP synthase, myosin, transducin, helicases, kinases and RecA." seems to imply that the latter proteins are not nucleotide binding proteins. Clearly anything that utilizes ATP or ADP is a nucleotide binding protein, even if that is not listed as its main function. Maybe "is present in diverse nucleotide-binding proteins, including . . . "

Is there a relationship between the Walker motifs and the Rossman fold, which also correlates with nucleotide binding, and consists of alternating sheet/helix? — Preceding unsigned comment added by Eaberry (talk • contribs) 18:31, 23 June 2012 (UTC)[reply]
