Engineering of a bacterial tyrosinase for improved catalytic efficiency towards D-tyrosine using random and site directed mutagenesis approaches
(Wiley-Blackwell, Hoboken, 2013)
The tyrosinase gene from Ralstonia solanacearum (GenBank NP518458) was subjected to random mutagenesis resulting in tyrosinase variants (RVC10 and RV145) with up to 3.2-fold improvement in kcat, 5.2-fold lower Km and 16-fold ...
Biodegradation of starch-graft-polystyrene and starch-graft-poly(methacrylic acid) copolymers in model river water / Biodegradacija kalemljenih kopolimera skroba i polistirena i skroba i poli(metakrilne kiseline) u rečnoj vodi
(Serbian Chemical Soc, Belgrade, 2013)
In this paper, a biodegradation study of grafted copolymers of cornstarch and polystyrene (PS) and cornstarch and poly(methacrylic acid) in model river water is described. These copolymers were obtained in the presence of ...
The effect of polyphosphate kinase gene deletion on polyhydroxyalkanoate accumulation and carbon metabolism in Pseudomonas putida KT2440
(Wiley-Blackwell, Hoboken, 2013)
The primary enzyme involved in polyphosphate (polyP) synthesis, polyP kinase (ppk), has been deleted in Pseudomonas putidaKT2440. This has resulted in a threefold to sixfold reduction in polyhydroxyalkanoate (PHA) accumulation ...
Highly efficient Michael-type addition of acetaldehyde to beta-nitrostyrenes by whole resting cells of Escherichia coli expressing 4-oxalocrotonate tautomerase
(Elsevier Sci Ltd, Oxford, 2013)
A novel whole cell system based on recombinantly expressed 4-oxalocrotonate tautomerase (4-OT) was developed and shown to be an effective biocatalyst for the asymmetric Michael addition of acetaldehyde to beta-nitrostyrenes. ...
Structure and antioxidant activity of beta-lactoglobulin-glycoconjugates obtained by high-intensity-ultrasound-induced Maillard reaction in aqueous model systems under neutral conditions
(Elsevier Sci Ltd, Oxford, 2013)
Sonication is a new processing technology in the dairy industry. The aim of this study was to test glycation of beta-lactoglobulin (BLG) in Maillard reaction (MR) induced by high-intensity ultrasound in aqueous solution ...
Toxic essential oils. Part III: Identification and biological activity of new allylmethoxyphenyl esters from a Chamomile species (Anthemis segetalis Ten.)
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
To determine the exact structure of previously tentatively identified minor essential-oil constituents of a Chamomile species (Antemis segetalis Ten. (Asteraceae)), we have synthesized a small combinatorial library of 54 ...
Lignin degradation by selected fungal species
(Elsevier Sci Ltd, Oxford, 2013)
As biological decomposition of plant biomass represents a popular alternative environmental-friendly and economically justified process, screening of ligninolytic enzyme systems of various fungal species is a topical study ...
Reactivity of (E)-4-aryl-4-oxo-2-butenoic acid arylamides toward 2-mercaptoethanol. A LFER study
(Springer Wien, Wien, 2013)
The reactivity of fifteen (E)-4-aryl-4-oxo-2-butenoic (aroylacrylic) acid arylamides toward thiols was studied, measuring the rate constants of the addition of model thiol nucleophile, 2-mercaptoethanol. The influence of ...
