摘要:
The present invention provides fungal xylanase and/or xylosidase enzymes suitable for use in saccharification reactions. The present invention provides xylanase and xylosidase enzymes suitable for use in saccharification reactions. The present application further provides genetically modified fungal organisms that produce xylanase(s) and/or xylosidase(s), as well as enzyme mixtures exhibiting enhanced hydrolysis of cellulosic material to fermentable sugars, enzyme mixtures produced by the genetically modified fungal organisms, and methods for producing fermentable sugars from cellulose using such enzyme mixtures. In some embodiments, the xylanase and xylosidase enzyme(s) are M. thermophila enzymes.
摘要:
The present invention provides methods for identifying bio-molecules with desired properties, or which are most suitable for acquiring such properties, from complex bio-molecule libraries or sets of such libraries. More specifically, some embodiments of the present invention provide methods for building sequence-activity models comprising multiplicative terms and using the models to guide directed evolution. In some embodiments, the sequence-activity models include one or more interaction terms, each of which including an interaction coefficient representing the contribution to activity of two or more defined residues. In some embodiments, the models describe relation between protein or nucleic acid sequences and protein activities. In some embodiments, the present invention also provides methods for preparing sequence-activity models, including but not limited to stepwise addition or subtraction techniques, Bayesian regression, ensemble regression and other methods. The present invention further provides digital systems and software for performing the methods provided herein.

摘要:
The present disclosure relates to biocatalytic methods or processes for the synthesis of acrylic acid and its derivatives, or other carboxylic acid compounds of the formula R—CO2H, wherein R is a carbon chain of 5 carbons or fewer, such as methacrylic acid or 3-hydroxypropionic acid. More specifically, the disclosure relates to methods of using an acyl-CoA hydrolase (such as a thioesterase) as a biocatalyst for the hydrolysis (and removal of the CoA moiety) of a substrate acyl-CoA compound to produce the corresponding carboxylic acid compound, such as acrylic acid. In some embodiments, the disclosure provides non-naturally occurring microorganisms that have been transformed with a heterologous acyl-CoA hydrolase, such as a thioesterase, that is capable of hydrolyzing an acyl-CoA produced in a pathway of the microorganism and produce the corresponding carboxylic acid compound, thereby allowing methods for the direct fermentative production of the compound.
