Cofactor requirement of ribosome-inactivating proteins from plants

Autor: Lucio Montanaro, Maurizio Brigotti, Domenica Carnicelli, Simonetta Sperti, Alessandra Pallanca, Paola Alvergna

Publikováno v: Journal of Experimental Botany. 48:1519-1523

A large number of type 1 ribosome-inactivating proteins (RIPs) from plants (families of Caryophyllaceae, Cucurbitaceae, Euphorbiaceae, Phytolaccaceae, and Poaceae) were examined for their requirement for ATP and supernatant factors for full activity.

Publikováno v: Biochemical Journal. 310:249-253

Inactivation of ribosomes by gelonin, a ribosome-inactivating protein with RNA N-glycosidase activity on 28 S rRNA, requires macromolecular cofactors present in post-ribosomal supernatants. One of these cofactors has been purified from a rat liver ex

Coordinate expression of Ca2+-ATPase slow-twitch isoform and of beta calmodulin-dependent protein kinase in phospholamban-deficient sarcoplasmic reticulum of rabbit masseter muscle

Autor: Alessandra Pallanca, Ernesto Damiani, Alfredo Margreth, Roberta Sacchetto

Publikováno v: FEBS letters. 481(3)

Modulation of sarcoplasmic reticulum (SR) Ca2+ transport by endogenous calmodulin-dependent protein kinase II (CaM K II) involves covalent changes of regulatory protein phospholamban (PLB), as a common, but not the only mechanism, in limb slow-twitch

Identity elements in bovine tRNA(Trp) required for the specific stimulation of gelonin, a plant ribosome-inactivating protein

Autor: Domenica Carnicelli, Simonetta Sperti, Simona Rizzi, Paola Accorsi, Alessandra Pallanca, Maurizio Brigotti, Lucio Montanaro

Ribosome-inactivating proteins (RIPs) are RNA-N-glycosidases widely present in plants that depurinate RNA in ribosomes at a specific universally conserved position, A4324, in the rat 28S rRNA. A small group of RIPs (cofactor-dependent RIPs) require A

Publikováno v: FEBS letters. 431(2)

Ribosome-inactivating proteins (RIP) are RNA- N -glycosidases widely diffused in plants which depurinate ribosomal RNA at a specific universally conserved position, A4324 in rat ribosomes. A small group of RIPs (cofactor-dependent RIPs) require ATP a

Uncompetitive inhibition by adenine of the RNA-N-glycosidase activity of ribosome-inactivating proteins

Autor: Lucio Montanaro, Maurizio Brigotti, Domenica Carnicelli, Paola Alvergna, Alessandra Pallanca, Simonetta Sperti, Raffaella Mazzaracchio

Publikováno v: Biochimica et biophysica acta. 1384(2)

Ricin is a member of the ribosome-inactivating protein (RIP) family with RNA-N-glycosidase activity which inactivates eukaryotic ribosomes by specifically removing adenine from the first adenosine of a highly conserved GAGA loop present in 28S rRNA.
