-
enzyme activity of prepuberal gilts rises with the onset of estrus, again just prior to ovulation on day 21, and during pregnancy. The activity is markedly elevated during the luteal and proestrous phases compared to the postovulatory phase. The highest specific activities occur at the proestrus when the follicle wall is undergoing breakdown
additional information
-
the enzyme is largely cell-associated during exponential growth in batch culture, but is progressively released by the bacteria before the cells enter stationary phase. The enzyme is completely cell-bound during growth in continuous culture
