Asymmetric behavior of archaeal prolyl-tRNA synthetase
(2005)Archaeal prolyl-tRNA synthetases differ from their bacterial counterparts: they contain an additional domain (about 70 amino acids) appended to the carboxy-terminus and lack an editing domain inserted into the class II ... -
Cold shock Y-box protein-1 proteolysis autoregulates its transcriptional activities
(2013)Background: The Y-box protein-1 (YB-1) fulfills pleiotropic functions relating to gene transcription, mRNA processing, and translation. It remains elusive how YB-1 shuttling into the nuclear and cytoplasmic compartments ... -
A freestanding proofreading domain is required for protein synthesis quality control in Archaea
(2004)Threonyl-tRNA synthetase (ThrRS) participates in protein synthesis quality control by selectively editing the misacylated species Ser-tRNAThr. In bacteria and eukaryotes the editing function of ThrRS resides in a highly ... -
A multifunctional RNA recognition motif in poly(A)-specific ribonuclease with cap and poly(A) binding properties
(2007)Poly(A)-specific ribonuclease (PARN) is an oligomeric, processive and cap-interacting 3′ exoribonuclease that efficiently degrades mRNA poly(A) tails. Here we show that the RNA recognition motif (RRM) of PARN harbors both ... -
Nicotinic cholinergic system and covid-19: In silico identification of an interaction between sars-cov-2 and nicotinic receptors with potential therapeutic targeting implications
(2020)While SARS-CoV-2 uses angiotensin converting enzyme 2 (ACE2) as the receptor for cell entry, it is important to examine other potential interactions between the virus and other cell receptors. Based on the clinical observation ... -
Ovine β-lactoglobulin at atomic resolution
(2014)The crystal structure of the triclinic form of the milk protein β-lactoglobulin from sheep (Ovis aries) at 1.1Å resolution is described together with a comparison of the triclinic structures of the low-pH bovine and high-pH ... -
Role of Arc1p in the modulation of yeast glutamyl-tRNA synthetase activity
(2005)Yeast methionyl-tRNA synthetase (MetRS) and glutamyl-tRNA synthetase (GluRS) possess N-terminal extensions that bind the cofactor Arc1p in trans. The strength of GluRS-Arc1p interaction is high enough to allow copurification ... -
Truncation and optimisation of peptide inhibitors of cyclin-dependent kinase 2-cyclin A through structure-guided design
(2009)The cyclin-dependent kinase 2-cyclin A complex is an important regulator of the DNA-synthesis phase of the mammalian cell cycle, which is frequently deregulated in cancer. Rather than blocking the ATP-binding site of the ...
