Methylotrophic extremophilic yeast Trichosporon sp.: a soil-derived isolate with potential applications in environmental biotechnology.
A yeast isolate revealing unique enzymatic activities and substrate-dependent polymorphism was obtained from autochthonous microflora of soil heavily polluted with oily slurries. By means of standard yeast identification procedures the strain was identified as Trichosporon cutaneum. Further molecular PCR product analyses of ribosomal DNA confirmed the identity of the isolate with the genus Tric...
متن کاملCharacterization of type 2 diacylglycerol acyltransferases in Chlamydomonas reinhardtii reveals their distinct substrate specificities and functions in triacylglycerol biosynthesis.
Diacylglycerol acyltransferases (DGATs) catalyze a rate-limiting step of triacylglycerol (TAG) biosynthesis in higher plants and yeast. The genome of the green alga Chlamydomonas reinhardtii has multiple genes encoding type 2 DGATs (DGTTs). Here we present detailed functional and biochemical analyses of Chlamydomonas DGTTs. In vitro enzyme analysis using a radiolabel-free assay revealed distinc...
متن کاملNovel ring cleavage products in the biotransformation of biphenyl by the yeast Trichosporon mucoides.
The yeast Trichosporon mucoides, grown on either glucose or phenol, was able to transform biphenyl into a variety of mono-, di-, and trihydroxylated derivatives hydroxylated on one or both aromatic rings. While some of these products accumulated in the supernatant as dead end products, the ortho-substituted dihydroxylated biphenyls were substrates for further oxidation and ring fission. These r...
متن کاملPurification, Characterization, and Substrate Specificities of Multiple Xylanases from Streptomyces sp. Strain B-12-2.
The endoxylanase complex from Streptomyces sp. strain B-12-2 was purified and characterized. The organism forms five distinct xylanases in the absence of significant cellulase activity when grown on oat spelt xylan. This is the largest number of endoxylanases yet reported for a streptomycete. On the basis of their physiochemical characteristics, they can be divided into two groups: the first gr...
متن کاملSubstrate specificities for yeast and mammalian cAMP-dependent protein kinases are similar but not identical.
The substrate specificity of the cAMP-dependent protein kinase (cAPK) from Saccharomyces cerevisiae has been investigated using synthetic peptides corresponding to the local phosphorylation site sequence around Ser-230 in the yeast transcriptional activator ADR1. ADR1 is required for the expression of the glucose-repressible alcohol dehydrogenase. Yeast cAPK (encoded by the TPK1 gene) phosphory...
