A model for codon position bias in RNA editing [PDF]

open access: yes, 2005
RNA editing can be crucial for the expression of genetic information via inserting, deleting, or substituting a few nucleotides at specific positions in an RNA sequence. Within coding regions in an RNA sequence, editing usually occurs with a certain bias

Template-directed biopolymerization: tape-copying Turing machines

open access: yes, 2012
DNA, RNA and proteins are among the most important macromolecules in a living cell. These molecules are polymerized by molecular machines. These natural nano-machines polymerize such macromolecules, adding one monomer at a time, using another linear ...

Functional characterization of a melon alcohol acyl-transferase gene family involved in the biosynthesis of ester volatiles. Identification of the crucial role of a threonine residue for enzyme activity [PDF]

open access: yes, 2005
Volatile esters, a major class of compounds contributing to the aroma of many fruit, are synthesized by alcohol acyl-transferases (AAT). We demonstrate here that, in Charentais melon (Cucumis melo var.

Neuron-Specific Glycine Metabolism Links Transfer RNA Epitranscriptomic Regulation to Complex Behaviors

open access: yesBiological Psychiatry Global Open Science
Background: The presence of treatment resistance in neuropsychiatric disease suggests that novel mechanism-based discoveries and therapies could benefit the field, with a viable candidate being transfer RNA (tRNA) epitranscriptomics.

Enjoy the Silence: Nearly Half of Human tRNA Genes Are Silent

open access: yesBioinformatics and Biology Insights, 2019
Transfer RNAs (tRNAs) are key components of the translation machinery. They read codons on messenger RNAs (mRNAs) and deliver the appropriate amino acid to the ribosome for protein synthesis.

Role of the Mitochondrial Genome During Early Development in Mice [PDF]

open access: yes, 1973
The role of the mitochondrial genome in early development and differentiation was studied in mouse embryos cultured in vitro from the two to four cell stage to the blastocyst (about 100 cells).

An acidic region of the 89K murine cytomegalovirus immediate early protein interacts with DNA [PDF]

open access: yes, 1992
The product of the ie 1 gene, the regulatory immediate early protein pp89 of murine cytomegalovirus (MCMV), interacts with core histones, which can mediate the association of pp89 with DNA.

Nucleolar Localization of HIV-1 Rev Is Required, Yet Insufficient for Production of Infectious Viral Particles. [PDF]

open access: yes, 2018
Combination antiretroviral therapy fails in complete suppression of HIV-1 due to drug resistance and persistent latency. Novel therapeutic intervention requires knowledge of intracellular pathways responsible for viral replication, specifically those ...

Endopolygalacturonase Genes from Colletotrichum lindemuthianum: Cloning of CLPG2 and Comparison of Its Expression to That of CLPG1 During Saprophytic and Parasitic Growth of the Fungus

open access: yesMolecular Plant-Microbe Interactions, 1997
Following the previous isolation of CLPG1, a gene encoding an endopolygalacturonase (endoPG) secreted into the culture filtrate of Colletotrichum lindemuthianum, we have isolated and sequenced an additional endoPG gene, CLPG2.

A single amino acid substitution in the alpha 3 domain of an H-2 class I molecule abrogates reactivity with CTL. [PDF]

open access: yes, 1987
We previously described a somatic cell expressing a variant H-2Dd molecule that did not serve as a target for alloreactive anti-Dd CTL. The mutant cell line had been isolated by its failure to express a serological epitope present on the H-2Dd alpha 3 ...
