The enzymatic activation of coenzyme B12

Dalton Transactions, 2006
The 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, 1977
As 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

2019
With 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, 2006
Directed 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 ...

Enzymatic activity of soils

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 ...
