Evolution of substrate specificity in the Nucleobase-Ascorbate Transporter (NAT) protein family [PDF]
, 2018 L-ascorbic acid (vitamin C) is an essential metabolite in animals and plants due to its role as an enzyme co-factor and antioxidant activity. In most eukaryotic organisms, L-ascorbate is biosynthesized enzymatically, but in several major groups ...

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 ...

Diverse physiological functions for dual-specificity MAP kinase phosphatases [PDF]
, 2006 A structurally distinct subfamily of ten dual-specificity (Thr/Tyr) protein phosphatases is responsible for the regulated dephosphorylation and inactivation of mitogen-activated protein kinase (MAPK) family members in mammals.

YscP, a key player in the type three secretion system of "Yersinia enterocolitica" [PDF]
, 2005 The Yersinia injectisome needle has a constant length of around 60nm. Mutants affected in the yscP gene display abnormally long needles, suggesting that needle length is genetically controlled and that YscP is involved in this process. First, both N- and

The substrate specificity of phospholipase A
Biochimica et Biophysica Acta (BBA) - Specialized Section on Lipids and Related Subjects, 1963 Investigations on variously modified analogues of phospholipids elucidated the following substrate characteristics for phospholipase A (Crotalus adamanteus). 1. 1. Within the class of α-phosphoglycerides l-isomers are readily hydrolysed, while d-α-phospholipids appeared not to be attacked. 2. 2.

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

Ultrasensitivity in phosphorylation-dephosphorylation cycles with little substrate [PDF]
, 2013 Cellular decision-making is driven by dynamic behaviours, such as the preparations for sunrise enabled by circadian rhythms and the choice of cell fates enabled by positive feedback.

Screening of DUB activity and specificity by MALDI-TOF mass spectrometry [PDF]
, 2014 Deubiquitylases (DUBs) are key regulators of the ubiquitin system which cleave ubiquitin moieties from proteins and polyubiquitin chains. Several DUBs have been implicated in various diseases and are attractive drug targets. We have developed a sensitive
