In the early 1960s , the Nashville sound began to be challenged by the rival Bakersfield sound on the country side and by the British Invasion on the pop side ; compounding these problems were the sudden deaths , in separate airplane crashes , of Patsy Cline and Jim Reeves , two of the Nashville Sound 's biggest stars . Nashville 's pop song structure became more pronounced and it morphed into what was called Countrypolitan - a smoother sound typified through the use of lush string arrangements with a real orchestra and often , background vocals provided by a choir . Countrypolitan was aimed straight at mainstream markets and it sold well throughout the later 1960s into the early 1970s . Among the architects of this sound were producers Billy Sherrill ( who was instrumental in shaping Tammy Wynette 's early career ) and Glenn Sutton . Artists who typified the countrypolitan sound initially included Wynette , Glen Campbell ( who recorded in Hollywood and not Nashville ) , Lynn Anderson , Charlie Rich , and Charley Pride , the latter being a rare example of a top - selling African - American country performer .

Nashville sound

Transition state analogs ( transition state analogues ) , are chemical compounds with a chemical structure that resembles the transition state of a substrate molecule in an enzyme - catalyzed chemical reaction . Enzymes interact with a substrate by means of strain or distortions , moving the substrate towards the transition state . Transition state analogs can be used as inhibitors in enzyme - catalyzed reactions by blocking the active site of the enzyme . Theory suggests that enzyme inhibitors which resembled the transition state structure would bind more tightly to the enzyme than the actual substrate . Examples of drugs that are transition state analog inhibitors include flu medications such as the neuraminidase inhibitor oseltamivir and the HIV protease inhibitors saquinavir in the treatment of AIDS .

Ex Output:
Transition state analog
