摘要:

The circadian rhythms of three peptide hydrolases and of maltase were studied in homogenates of rat intestine and in fractions of brush border membrane. Changes in the protein ratio between the brush border membrane (BBM) fraction and the crude homogenate are responsible for the overall rhythm. Differences in amplitude and acrophase for the different enzymes, however, indicate a difference in stability of these hydrolases.
