6593001-1	1984	A series of N-alkylmaleimides, varying in chain length from N-ethylmaleimide and N-butyl to N-octyl, inclusive, was shown to effectively inactivate rat ovarian 20 alpha-hydroxysteroid dehydrogenase at pH 7.7, 25 degrees C. The apparent second-order rate constants for inactivation were observed to increase with increasing chain length of the N-alkylmaleimide used.	Ethylmaleimide	60-76	aldo-keto reductase family 1, member C3	Rattus norvegicus	160-197
