Abstract

Purine nucleoside phosphorylase (EC 2.4.2.1) from Bacillus cereus T was examined at hourly intervals during growth and sporulation. The enzyme has maximal activity in extracts prepared from cells during stages I and II. The activity during exponential growth is only 6.6% of the maximum and that in free spores is only 3.3%. Conservation of the purine nucleoside phosphorylase during sporulation is apparent as shown by the gradual increase in heat resistance.
