The present invention relates to polypeptides having xylanase activity and nucleic acid sequences encoding such polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the nucleic acid constructs as well as methods for producing and using the polypeptides. One specific application of the xylanase is the selective hydrolysis of pentose sugar components of hemicellulose-containing plant biomass. The nucleotide sequence may be used for the production of the xylanase or optimized mutants thereof.

An RNA ligase derived from bacteriophage TS2126 which infects, nucleic acids comprising nucleotide sequences of open reading frame (ORF) and polypeptides encoded by the nucleic acids, are described.

Thermostable RNA ligase from thermus phage

A novel bacteriophage RM 378 of , the nucleic acids of its genome, nucleic acids comprising nucleotide sequences of open reading frames (ORFs) of its genome, and polypeptides encoded by the nucleic acids, are described.

Disclosed are variant thermostable cellulases, nucleic acids encoding the variants and methods for producing the variants. The variant thermostable cellulases have the amino acid sequence of a glycosyl hydrolase of family 12 wherein one or more amino acid residues which are not part of the catalytic domain are deleted. In specific embodiments, the variant thermostable cellulase is a variant of Cel12A of
