The system I cytochrome c biogenesis pathway requires CcmD, a small polypeptide of 69 residues in Escherichia coli. Here it is shown that CcmD is a component of the CcmABC ATP-binding cassette transpo...Read More
Comparing the xylose reductase/xylitol dehydrogenase and xylose isomerase pathways in arabinose and xylose fermenting Saccharomyces cerevisiae strains.
Ethanolic fermentation of lignocellulosic biomass is a sustainable option for the production of bioethanol. This process would greatly benefit from recombinant Saccharomyces cerevisiae strains also ab...Read More
During the past few years, substantial progress has been made to understand the enzymology and regulation of nucleotide sugar interconversion reactions that are irreversible in vivo on thermodynamic g...Read More
L: -Ribose is a rare and expensive sugar that can be used as a precursor for the production of L: -nucleoside analogues, which are used as antiviral drugs. In this work, we describe a novel way of pro...Read More
An Escherichia coli strain, ZUC99(pATX210), which can produce xylitol from L-arabinose at a high yield, has been created by introducing a new bioconversion pathway into the cells. This pathway consist...Read More
Immobilization of Bacillus licheniformis L: -arabinose isomerase (BLAI) on aminopropyl glass modified with glutaraldehyde (4 mg protein g support?1) was found to enhance the enzyme activity. The immob...Read More
Characterization of a recombinant cellobiose 2-epimerase from Caldicellulosiruptor saccharolyticus and its application in the production of mannose from glucose.
A putative N-acyl-D-glucosamine 2-epimerase from Caldicellulosiruptor saccharolyticus was cloned and expressed in Escherichia coli. The recombinant enzyme was identified as a cellobiose 2-epimerase by...Read More
Hyperthermophilic L-arabinose isomerases (AIs) are useful in the commercial production of D-tagatose as a low-calorie bulk sweetener. Their catalysis and thermostability are highly dependent on metals...Read More
Recombineering-mediated tagging of Drosophila genomic constructs for in vivo localization and acute protein inactivation.
Studying gene function in the post-genome era requires methods to localize and inactivate proteins in a standardized fashion in model organisms. While genome-wide gene disruption and over-expression e...Read More
The cane toad, Bufo (Chaunus) marinus, is one of the most notorious vertebrate pests introduced into Australia over the last 200 years and, so far, efforts to identify a naturally occurring B. marinus...Read More
The essential Escherichia coli gene ygjD belongs to a universally conserved group of genes whose function has been the focus of a number of recent studies. Here, we put ygjD under control of an induci...Read More
Characterization of RimO, a new member of the methylthiotransferase subclass of the radical SAM superfamily.
RimO, encoded by the yliG gene in Escherichia coli, has been recently identified in vivo as the enzyme responsible for the attachment of a methylthio group on the beta-carbon of Asp88 of the small rib...Read More
The arabinose-inducible P(BAD) promoter suffers from all-or-none gene expression in which cells harboring the natively controlled arabinose transport gene (araE) are either induced or uninduced, the r...Read More
D-tagatose is a natural monosaccharide with a low caloric value and has an anti-hyperglycemiant effect. This hexose has potential applications both in pharmaceutical and agro-food industries. However,...Read More
