Abstract

Proteins synthesized during the encystment of Azotobacter vinelandii were radiolabeled with [35S]methionine and analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Pulse labeling was used to demonstrate that early encystment-specific proteins were beginning to be synthesized at 2 h and reached peak levels about 12 h after initiation of encystment. One such protein was identified as a beta-ketoacyl acyl-carrier protein synthase. The concentration of early proteins began to decrease at 16 h, when intermediate proteins specific to the differentiation process began to be synthesized. The cessation of synthesis of intermediate proteins began at 20 h postinitiation, and the labeling pattern of proteins then remained constant throughout the remaining 4 days of encystment.
