Toxins, 2016 Ricin is a type 2 ribosome-inactivating protein (RIP), containing a catalytic A chain and a lectin-like B chain. It inhibits protein synthesis by depurinating the N-glycosidic bond at α-sarcin/ricin loop (SRL) of the 28S rRNA, which thereby prevents the ...

Improvement of the Pharmacological Properties of Maize RIP by Cysteine-Specific PEGylation
Toxins, 2016 To improve the pharmacological properties of maize ribosome-inactivating protein (maize RIP) for targeting HIV-infected cells, the previously engineered TAT-fused active form of maize RIP (MOD) was further engineered for cysteine-directed PEGylation.

Small-molecule inhibitor leads of ribosome-inactivating proteins developed using the doorstop approach. [PDF]
PLoS ONE, 2011 Ribosome-inactivating proteins (RIPs) are toxic because they bind to 28S rRNA and depurinate a specific adenine residue from the α-sarcin/ricin loop (SRL), thereby inhibiting protein synthesis.

Ribosome-inactivating proteins (RIPs) and their important health promoting property
RSC Advances, 2016 Ribosome-inactivating proteins (RIPs), widely present in plants, certain fungi and bacteria, can inhibit protein synthesis by removing one or more specific adenine residues from the large subunit of ribosomal RNAs (rRNAs).
