Predicting the substrate specificity of a glycosyltransferase implicated in the production of phenolic volatiles in tomato fruit [PDF]
, 2011 The volatile compounds that constitute the fruit aroma of ripe tomato (Solanum lycopersicum) are often sequestered in glycosylated form. A homology-based screen was used to identify the gene SlUGT5, which is a member of UDP-glycosyltransferase 72 family ...

Substrate specificity of human MCPIP1 endoribonuclease
Scientific Reports, 2018 MCPIP1, also known as Regnase-1, is a ribonuclease crucial for regulation of stability of transcripts related to inflammatory processes. Here, we report that MCPIP1 acts as an endonuclease by degrading several stem-loop RNA structures and single-stranded

Substrate Specificity of Recombinant Ser/Thr Protein Kinase
Bio-Protocol, 2015 Protein kinases are enzymes that phosphorylate proteins in a cell. Determination of kinase activity in reactions of phosphorylation is a very convenient way for a biochemical characterization of this group of enzymes.

Evolution of substrate specificity in a retained enzyme driven by gene loss. [PDF]
, 2017 The connection between gene loss and the functional adaptation of retained proteins is still poorly understood. We apply phylogenomics and metabolic modeling to detect bacterial species that are evolving by gene loss, with the finding that ...

Substrate Specificity of Chlorophyllase [PDF]
Plant Physiology, 1975 Apparent Km and V(max) values were obtained for hydrolysis of methyl and ethyl chlorophyllides a, methyl and ethyl pheophorbide a, and 9-hydroxymethyl pheophorbide a by chlorophyllase from Ailanthus altissima. Analysis of substrate specificity data for chlorophyllase indicates that the presence of a 9-keto group and a methyl alcohol group esterified at

On the substrate specificity of human CYP27A1
Journal of Lipid Research, 2003 The mitochondrial sterol 27-hydroxylase (CYP27A1) is required for degradation of the C27-sterol side chain in bile acid biosynthesis. CYP27A1 seems, however, to have roles beyond this, as illustrated by patients with a deficient sterol 27-hydroxylase due

Phosphotyrosine Substrate Sequence Motifs for Dual Specificity Phosphatases. [PDF]
PLoS ONE, 2015 Protein tyrosine phosphatases dephosphorylate tyrosine residues of proteins, whereas, dual specificity phosphatases (DUSPs) are a subgroup of protein tyrosine phosphatases that dephosphorylate not only Tyr(P) residue, but also the Ser(P) and Thr(P ...

Substrate specificity of Ty1 integrase [PDF]
Journal of Virology, 1995 Integration of the Saccharomyces cerevisiae retrotransposon Ty1 requires the element-encoded integrase (IN) protein, which is a component of cytoplasmic virus-like particles (VLPs). Using purified recombinant Ty1 IN and an oligonucleotide integration assay based on Ty1 long terminal repeat sequences, we have compared IN activity on substrates having ...
