Ribosome-inactivating proteins.
The main results of the research performed in the last 30 years on ribosome-inactivating proteins (RIPs) are reviewed, with emphasis on the new, controversial and uncertain aspects. The nature, distribution, mechanism of action and properties of these proteins are briefly reported, together with their possible applications. A pattern appears of a still largely unexplored subject, whose role in ...
متن کاملRibosome-inactivating proteins
Ribosome-inactivating proteins (RIPs) were first isolated over a century ago and have been shown to be catalytic toxins that irreversibly inactivate protein synthesis. Elucidation of atomic structures and molecular mechanism has revealed these proteins to be a diverse group subdivided into two classes. RIPs have been shown to exhibit RNA N-glycosidase activity and depurinate the 28S rRNA of the...
متن کاملA ribosome-inactivating protein in a Drosophila defensive symbiont.
Vertically transmitted symbionts that protect their hosts against parasites and pathogens are well known from insects, yet the underlying mechanisms of symbiont-mediated defense are largely unclear. A striking example of an ecologically important defensive symbiosis involves the woodland fly Drosophila neotestacea, which is protected by the bacterial endosymbiont Spiroplasma when parasitized by...
متن کاملRibosome-Inactivating and Related Proteins
Ribosome-inactivating proteins (RIPs) are toxins that act as N-glycosidases (EC 3.2.2.22). They are mainly produced by plants and classified as type 1 RIPs and type 2 RIPs. There are also RIPs and RIP related proteins that cannot be grouped into the classical type 1 and type 2 RIPs because of their different sizes, structures or functions. In addition, there is still not a uniform nomenclature ...
متن کاملCinnamomin--a versatile type II ribosome-inactivating protein.
Ribosome-inactivating proteins (RIPs) are a group of toxic proteins that can specifically act on the universally conserved sarcin/ricin domain (S/R domain) of the largest RNA in ribosome and thus irreversibly inactivate ribosome for protein synthesis. Cinnamomin is a multifunctional type II RIP isolated in our laboratory from the mature seeds of the camphor tree. This protein has been extensive...
