Enzyme Kinetics Flashcards
uses of enzyme kinetics?
- characterize new enzymes, activity, inhibitors
- screening compound and cell libraries
- measuring activity, sub conc, inhib conc
enzyme bioassay set up
stock solutions of enzyme and substrate
buffer
additives (cofactor, ions)
reaction stop agent
why do we screen enzyme libraries?
potential inhibitors/drugs, recomb enzymes
enzyme inhibitor drugs?
statins, hypertension
what is an enzyme inhibitor?
decreases rate of enzyme catalysed reaction
how does an enzyme inhibitor work?
influences the binding of S, turnover number, or total conc of active enzymes
what is a stopped enzyme assay?
reaction occurs for a set time period, amount of product is determined
how is an enzyme assay stopped?
denaturation, ie acid/base, heat, inhibitors, EDTA, cold
benefits of point of care testing
small sample, minimally invasive, rapid results, fast turnaround, reduced costs
