Structure and evolution of ricin B chain Nature

WebAcids Res. 13:8019). A second group of cDNA clones, represented by pBL-3, encode a hybrid protein (ricin E), having a ricin-like A chain and N-terminal half of the B chain and an RCA (Ricinus communis agglutinin)-like C-terminal half of the B chain. AB - Two classes of ricin cDNA clones have been identified and sequenced. WebWe report here that comparison of amino-acid sequence data with high-resolution structure analysis of the ricin B subunit shows it to be the product of a series of gene duplications. The modern protein has two sugar-binding domains, each of which is composed of three copies of a more ancient galactose-binding peptide of about 40 residues. skype app for logitech hd webcam c920
