Microwave Activation of Enzymatic Catalysis
Journal of the American Chemical Society, 2008Microwave irradiation can be used to regulate biocatalysis. Herein, the utilization of hyperthermophilic enzymes in a microwave reactor is reported. While these enzymes are inactive at low temperatures, they can be activated with microwave irradiation.

Enzymatic activity of aphroproteins.
Biochemistry. Biokhimiia, 1999Chitinase and proteinase activities were found in aphroproteins excreted by larvae of the cicada Aphrophora costalis Mats; this accounts for their fungicidal effect. Aphroproteins did not show DNase or RNase activities and did not exhibit properties of proteinase inhibitors.

Enzymatic activity in the activated-sludge floc matrix
Applied Microbiology and Biotechnology, 1995The enzymatic activity of activated sludge was investigated with special emphasis on the localization of the enzymes in the sludge floc matrix. Activated sludge from an advanced activated-sludge treatment plant, performing biological N and P removal, was used. An enzymatic fingerprint was established using a panel of six different enzymes.

The enzymatic activation of coenzyme B12
Dalton Transactions, 2006The enzymatic "activation" of coenzyme B12 (5'-deoxyadenosylcobalamin, AdoCbl), in which homolysis of the carbon-cobalt bond of the coenzyme is catalyzed by some 10(9)- to 10(14)-fold, remains one of the outstanding problems in bioinorganic chemistry.

Enzymatic activities of activated sludge
European Journal of Applied Microbiology, 1977As a potential measure of active biomass in an automated and continuous system, enzyme activities of activated sludge were sought that would allow a rapid and accurate determination. Using p-nitrophenylphosphate, bis-p-nitrophenylphosphate, p-nitrophenyl-α- and β-D-gluco- or galactopyranosides, and the p-nitroanilides of L-alanine, L-leucine, L-lysine,

Enzymatic activity in single cells
2019With the increasing recognition of the importance in addressing cell-to-cell variations for the understanding of complex biological systems, single cell analyses are becoming increasingly important. Presented in this chapter is a highly sensitive approach capable of measuring human topoisomerase 1 (TOP1) activity in single CD133 positive DLD-1 cells ...

Fluorescence Activated Cell Sorting for Enzymatic Activity
Combinatorial Chemistry & High Throughput Screening, 2006Directed evolution is a reliable method for protein engineering and as a tool for investigating structure/function relationships. A key for a successful directed evolution experiment is oftentimes the screen. Fluorescence activated cell sorting (FACS) is powerful high-throughput screening approach to isolate and identify mutants from large protein ...

Geoderma, 1974
Abstract Enzymatic activity as dependent upon soil acidity, calcareousness, particle-size distribution, temperature, adsorption and seasonal dynamics has been investigated under different soil-climatic conditions in Armenia. The results indicate broad applicability of enzymatic reactions for studying various aspects of soil science such as soil ...
