The fleeting union of the enzyme and the substance on which it acts holds a key to our understanding of life processes. Many ingenious techniques are in use today to isolate it for study ...

THE exact intermediate steps in the breakdown caused by ribonuclease enzymic activity awaits clarification in spite of the many methods currently used in the measurement of ribonuclease activity.

This illustration depicts the process of enzyme catalysis. The enzyme (blue) binds to its substrate (red) to form an enzyme-substrate complex. The enzyme then catalyzes the conversion of the substrate ...

Now that more complex aspects of biology are becoming ... chemically with their substrates to form covalently bonded enzyme-substrate intermediates has done more than anything else to dispel ...
