Abstract:
Bovine pancreatic RNase A (ribonuclease A) aggregates to form various types of catalytically active oligomers during lyophilization from aqueous acetic acid solutions. Each oligomeric species is present in at least two conformational isomers. The structures of two dimers and one of the two trimers have been solved, while plausible models have been proposed for the structures of a second trimer and two tetrameric conformers. In this review, these structures, as well as the general conditions for RNase A oligomerization, based on the well known 3D (three-dimensional) domain-swapping mechanism, a

Abstract:
Protein oligomerization is key to countless physiological processes, but also to abnormal amyloid conformations implicated in over 25 mortal human diseases. Human Angiogenin (h-ANG), a ribonuclease A family member, produces RNA fragments that regulate ribosome formation, the creation of new blood vessels and stress granule function. Too little h-ANG activity leads to abnormal protein oligomerization, resulting in Amyotrophic Lateral Sclerosis (ALS) or Parkinson’s disease. While a score of disease linked h-ANG mutants has been studied by X-ray diffraction, some elude crystallization. There is a

Abstract:
The N1/T1 RNase superfamily comprises enzymes with well-established antitumor effects, such as ribotoxins secreted by fungi, primarily byAspergillusandPenicilliumspecies, and bacterial RNase secreted byB. pumilus(binase) andB. amyloliquefaciens(barnase). RNase is regarded as an alternative to classical chemotherapeutic agents due to its selective cytotoxicity towards tumor cells. New RNase with a high degree of structural similarity with binase (73%) and barnase (74%) was isolated and purified fromBacillus licheniformis(balifase, calculated molecular weight 12421.9 Da, pI 8.91).

Abstract:
Inflammasomes are cytosolic innate immune sensors of pathogen infection and cellular damage that induce caspase-1–mediated inflammation upon activation. Although inflammation is protective, uncontrolled excessive inflammation can cause inflammatory diseases and can be detrimental, such as in coronavirus disease (COVID-19). However, the underlying mechanisms that control inflammasome activation are incompletely understood. Here we report that the leucine-rich repeat (LRR) protein ribonuclease inhibitor (RNH1), which shares homology with LRRs of NLRP (nucleotide-binding oligomerization domain, l

Abstract:
Poly(A)-specific ribonuclease (PARN) is a deadenylase that degrades the poly(A) tail of eukaryotic mRNA. PARN also interacts with the 5’-cap structure of the mRNA. The binding of the cap structure enhances the deadenylation rate. PARN has previously been described as a dimer. We have studied PARN with size exclusion chromatography to investigate the oligomeric composition and revealed oligomeric compositions of PARN that are larger than dimeric PARN. Deadenylation assays have been used to measure the cap stimulated activity of PARN. The deadenylation assays showed that the cap stimulated activ

Abstract:
The three dimensional domain swapping (3D-DS) mechanism represents a useful strategy that proteins can follow to self-associate. This mechanism requires the presence of a flexible portion that generally links the N- and/or C-terminus of the protein to its core. This portion, called hinge loop, can adopt different conformations as a function of the environmental conditions and allows the mentioned N- and/or C-terminal domains to be detached from the protein core and to be swapped with an identical domain of another protomer. This induces the formation of dimer(s) or larger oligomer(s) that ofte

"Zero-length" dimers of ribonuclease A, a novel type of dimers formed by two RNase A molecules bound to each other through a zero-length amide bond [Simons, B.L. et al. (2007) Proteins 66, 183-195], were analyzed, and tested for their possible in vitro cytotoxic activity. Results: (i) Besides dimers, also trimers and higher oligomers can be identified among the products of the covalently linking reaction. (ii) The "zero-length" dimers prepared by us appear not to be a unique species, as was instead reported by Simons et al. The product is heterogeneous, as shown by the involvement in the amide
