Activity
New active sites can be introduced into naturally occurring enzymes by the chemical modification of specific acidic residue. The resultant enzymes can have catalytic activities very different from those of the corresponding native enzymes. Thus, it is now possible to enhance the catalytic versatility of existing enzymes through the process of “chemical mutation” of the active site.

This morning the radio delivered a string of local events, as usual. Not as usual was a single event that stood out as particularly interesting, and which a future novelist has no doubt filed away in a “To Use” word processing document.
The event involved three men who died of sulphur dioxide poisoning in a well. It happened somewhere in or near New York City. Freak causes of death themselves are disconcertingly common. The interesting facts here are as follows:
•A father and son were working on the well
•The son fell in
•His father went after him with a ladder
•Both were overcome by toxic fumes
•I am not sure how the third man died
•There exist wells in or near NYC, and some of them are toxicThe brevity of the radio report gave the event a bare-bones feeling, as though it were a biblical account or a fable. I could not find an online account of the accident either, so soon after hearing the report its details began to waver in my mind and become more of a tale than a briefing.
