| Addtional Information | FUNCTION:The A chain is responsible for inhibiting protein synthesis through the catalytic inactivation of 60S ribosomal subunits by removing adenine from position 4,324 of 28S rRNA.Abrin-a is more toxic than ricin.FUNCTION:The B chain is a galactose-specific lectin that facilitates the binding of abrin to the cell membrane that precedes endocytosis.CATALYTIC ACTIVITY:Endohydrolysis of the N-glycosidic bond at one specific adenosine on the 28S rRNA.SUBUNIT:Disulfide-linked dimer of A and B chains.DOMAIN:The B chain is composed of two domains, each domain consists of 3 homologous subdomains (alpha, beta, gamma).SIMILARITY:In the N-terminal section; belongs to the ribosome- inactivating protein family. Type 2 RIP subfamily.SIMILARITY:Contains 2 ricin B-type lectin domains. |
