Abstract XynR is a thermostable alkaline GH10 xylanase, for which we have previously examined the effects of saturation mutagenesis at position 315 on enzyme alkaliphily, and found that at pH 10, the activities of variants could be ordered as follows

Abstract mRNA export is an essential pathway for the regulation of gene expression. In humans, closely related RNA helicases, UAP56 and URH49, shape selective mRNA export pathways through the formation of distinct complexes, known as apo-TREX and apo

Abstract Gram-negative Sphingomonas sp. strain A1 exhibits positive chemotaxis toward acidic polysaccharide pectin. SPH1118 has been identified as a pectin-binding protein involved in both pectin chemotaxis and assimilation. Here we show tertiary str

The authors solve the crystal structure of OsGA3ox2 and predict that of OsGA3ox1. These enzymes catalyze the final step in the biosynthesis of gibberellin, one of the plant hormones. Evolutionary analysis combined with the new structure reveal import

Makoto Hibi et al. report a novel three-component monooxygenase system in Rhodococcus wratislaviensis. This enzyme catalyzes the activation of an inert C–H bond and may be potentially important as a biocatalyst for industrial applications.

Enzymatic inactivation of gibberellins and auxin, via GA2ox3 and DAO respectively, contributes to hormone homeostasis in plants. Here Takehara et al. show that both enzymes multimerize in a substrate-concentration-dependent manner, and that this mult

Abstract Glycosaminoglycans (GAGs), such as hyaluronan, chondroitin sulfate, and heparin, constitute mammalian extracellular matrices. The uronate and amino sugar residues in hyaluronan and chondroitin sulfate are linked by 1,3-glycoside bond, while

Certain bacterial species target the polysaccharide glycosaminoglycans (GAGs) of animal extracellular matrices for colonization and/or infection. GAGs such as hyaluronan and chondroitin sulfate consist of repeating disaccharide units of uronate and a

Lipid antigens have been added to the antigenic repertoire in recent years. Here, the authors have identified Mamu-B*098 as a lipopeptide antigen presenting molecule and using structural and biochemical analysis have shown that it has a different ant

Thaumatin, an intensely sweet-tasting protein, elicits sweet taste with a threshold of only 50 nM. Previous studies from our laboratory suggested that the complex model between the T1R2-T1R3 sweet receptor and thaumatin depends critically on the comp
