ALPHA AMYLASE DEVELOPMENT IN EMBRYOS OF CRASSOSTREA VIRGINICA

ROBERT E. BLACK 1 and E. T. PENGELLEY 1

1 Department of Biology and Virginia Institute of Marine Science, College of William and Mary, Williamsburg, Virginia

Alpha amylase activity is absent from developmental stages of the oyster up to the straight-hinge veliger. Its development after this stage parallels the development of the intestine. After reaching a maximum at 37 hours, the enzyme drops sharply in activity, presumably because of starvation. The larval enzyme has the same pH optimum and substrate specificity as that of the adult, but the energy of activation is somewhat lower than that of the adult.
