Mechanism and site of action of a ribosome‐inactivating protein type 1 from Dianthus barbatus which inactivates Escherichia coli ribosomes

open access: yesFEBS Letters, 1992
A single chain ribosome‐inactivating protein with RNA N‐glycosidase activity, here named Dianthin 29, was isolated from leaves of Dianthus barbatus L. Incubation of intact Escherichia coli ribosomes with Dianthin 29 and subsequent aniline treatment of the isolated rRNA releases a rRNA fragment of 243 nucleotides from 23 S rRNA.

Preparation of an antitumor and antivirus agent: chemical modification of α-MMC and MAP30 from Momordica Charantia L. with covalent conjugation of polyethyelene glycol [PDF]

open access: yes, 2012
Background: Alpha-momorcharin (α-MMC) and momordica anti-HIV protein (MAP30) derived from Momordica charantia L. have been confirmed to possess antitumor and antivirus activities due to their RNA-N-glycosidase activity. However, strong immunogenicity and

Lectin domains at the frontiers of plant defense [PDF]

open access: yes, 2014
Plants are under constant attack from pathogens and herbivorous insects. To protect and defend themselves, plants evolved a multi-layered surveillance system, known as the innate immune system.

Riproximin Exhibits Diversity in Sugar Binding, and Modulates some Metastasis-Related Proteins with Lectin like Properties in Pancreatic Ductal Adenocarcinoma

open access: yesFrontiers in Pharmacology, 2020
Riproximin (Rpx) is a type II ribosome-inactivating protein with specific anti-proliferative activity. It was purified from Ximenia americana by affinity chromatography using a resin coupled with lactosyl residues.

Involvement of loops 2 and 3 of alpha-sarcin on its ribotoxic activity [PDF]

open access: yes, 2015
Ribotoxins are a family of fungal ribosome-inactivating proteins displaying highly specific ribonucleolytic activity against the sarcin/ricin loop (SRL) of the larger rRNA, with a-sarcin as its best-characterized member.

Immunoconjugates made of an anti-EGF receptor monoclonal antibody and type 1 ribosome-inactivating proteins from Saponaria ocymoides or Vaccaria pyramidata.

open access: yesBritish Journal of Cancer, 1997
The present paper describes two immunoconjugates consisting of an anti-epidermal growth factor receptor (EGFR) monoclonal antibody (MAb), named Mint5, covalently linked to the type 1 ribosome-inactivating proteins (RIPs) ocymoidine (Ocy) and pyramidatine

Structure and Activity of a Cytosolic Ribosome-Inactivating Protein from Rice

open access: yesToxins, 2019
Ribosome-inactivating proteins (RIPs) are cytotoxic enzymes that inhibit protein translation by depurinating ribosomal RNA. Although most plant RIPs are synthesized with leader sequences that sequester them away from the host ribosomes, several RIPs from
