Assembly stoichiometry of bacterial selenocysteine synthase and SelC (tRNAsec)
(Elsevier BVAmsterdam, 2013-04)
In bacteria selenocysteyl-tRNAsec (SelC) is synthesized by selenocysteine synthase (SelA). Here we show by fluorescence anisotropy binding assays and electron microscopical symmetry analysis that the SelA-tRNAsec binding ...
The Specific Elongation Factor to Selenocysteine Incorporation in Escherichia coli: Unique tRNASec Recognition and its Interactions
(2021-11-19)
Several molecular mechanisms are involved in the genetic code interpretation during translation, as codon degeneration for the incorporation of rare amino acids. One mechanism that stands out is selenocysteine (Sec), which ...
Formation of a ternary complex for selenocysteine biosynthesis in bacteria
(The American Society for Biochemistry and Molecular Biology, 2015-09-16)
The synthesis of selenocysteine-containing proteins (selenoproteins) involves the interaction of Selenocysteine Synthase (SelA), tRNA (tRNASec), Selenophosphate Synthetase (SelD, SPS), a specific elongation factor (SelB) ...
Trypanosomatid selenophosphate synthetase structure, function and interaction with selenocysteine lyase
(2020-10-01)
Eukaryotes from the Excavata superphylum have been used as models to study the evolution of cellular molecular processes. Strikingly, human parasites of the Trypanosomatidae family (T. brucei, T. cruzi and L. major) conserve ...

Estudos moleculares da Selenocisteína Sintase (SELA) de Escherichia coli.
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Genética Evolutiva e Biologia Molecular - PPGGEv, 2005-05-05)
The study of translation processes attracts the interest of a wide range of
research groups due to its main role in general cellular metabolism. In
particular, the investigation of new amino acid residues, such as ...
Identification of SL addition trans-splicing acceptor sites in the internal transcribed spacer I region of pre-rRNA in Leishmania (Leishmania) amazonensis
(Instituto Oswaldo Cruz, Ministério da Saúde, 2012)
Trypanosomatidae is a family of early branching eukaryotes harbouring a distinctive repertoire of gene expression strategies. Functional mature messenger RNA is generated via the trans-splicing and polyadenylation processing ...
An efficient protocol for the production of tRNA-free recombinant Selenocysteine Synthase (SELA) from Escherichia coli and its biophysical characterization
(ElsevierAmsterdam, 2013-03)
Selenocysteine Synthase (SELA, E.C. 2.9.1.1) from Escherichia coli is a homodecamer pyridoxal-5′-phosphate containing enzyme responsible for the conversion of seryl-tRNA sec into selenocysteyl-tRNA sec in the biosynthesis ...
