Expression of the C-terminal family 22 carbohydratebinding module of xylanase 10B of Clostridium themocellum in tobacco plant [PDF]
Carbohydrate-binding modules have been shown to alter plant cell wall structural architecture. Hence, they have the potential application of being used to engineer the plant to produce tailor-made natural fibers in the cell wall.

Many Activities, One Structure: Functional Plasticity of Ribozyme Folds
Catalytic RNAs, or ribozymes, are involved in a number of essential biological processes, such as replication of RNA genomes and mobile genetic elements, RNA splicing, translation, and RNA degradation.

Kinetic analysis of an efficient DNA-dependent TNA polymerase. [PDF]
alpha-l-Threofuranosyl nucleoside triphosphates (tNTPs) are tetrafuranose nucleoside derivatives and potential progenitors of present-day beta-d-2'-deoxyribofuranosyl nucleoside triphosphates (dNTPs).

The Origin of Life: Models and Data. [PDF]
A general framework for conventional models of the origin of life (OOL) is the specification of a 'privileged function.' A privileged function is an extant biological function that is excised from its biological context, elevated in importance over other

The RNA-dependent RNA polymerases (RdRPs) encoded by the RNA viruses are a unique class of nucleic acid polymerases. Each viral RdRP contains a 500–600 residue catalytic module with palm, fingers, and thumb domains forming an encircled human right hand ...

Evolution of RNA-protein interactions: non-specific binding led to RNA splicing activity of fungal mitochondrial tyrosyl-tRNA synthetases. [PDF]
The Neurospora crassa mitochondrial tyrosyl-tRNA synthetase (mtTyrRS; CYT-18 protein) evolved a new function as a group I intron splicing factor by acquiring the ability to bind group I intron RNAs and stabilize their catalytically active RNA structure ...

The Exosome Subunit Rrp44 Plays a Direct Role in RNA Substrate Recognition [PDF]
The exosome plays key roles in RNA maturation and surveillance, but it is unclear how target RNAs are identified. We report the functional characterization of the yeast exosome component Rrp44, a member of the RNase II family.

The structure of an RNAi polymerase links RNA silencing and transcription.
RNA silencing refers to a group of RNA-induced gene-silencing mechanisms that developed early in the eukaryotic lineage, probably for defence against pathogens and regulation of gene expression.

Robustness and modularity properties of a non-covalent DNA catalytic reaction [PDF]
The biophysics of nucleic acid hybridization and strand displacement have been used for the rational design of a number of nanoscale structures and functions. Recently, molecular amplification methods have been developed in the form of non-covalent DNA

Prokaryotic Argonautes – variations on the RNA interference theme
The discovery of RNA interference (RNAi) has been a major scientific breakthrough. This RNA-guided RNA interference system plays a crucial role in a wide range of regulatory and defense mechanisms in eukaryotes.
