Time course of purine nucleoside phosphorylase occurrence in sporulation of Bacillus cereus.
نویسنده
چکیده
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.

Structural basis of the substrate specificity of Bacillus cereus adenosine phosphorylase.
Purine nucleoside phosphorylases catalyze the phosphorolytic cleavage of the glycosidic bond of purine (2'-deoxy)nucleosides, generating the corresponding free base and (2'-deoxy)-ribose 1-phosphate. Two classes of PNPs have been identified: homotrimers specific for 6-oxopurines and homohexamers that accept both 6-oxopurines and 6-aminopurines. Bacillus cereus adenosine phosphorylase (AdoP) is ...
متن کاملDissecting interactions between nucleosides and germination receptors in Bacillus cereus 569 spores.
Bacillus cereus 569 spores germinate either with inosine as a sole germinant or with a combination of nucleosides and L-alanine. Whereas the inosine-only germination pathway requires the presence of two different germination receptors (GerI and GerQ) to be activated, the nucleoside/alanine germination pathway only needs one of the two receptors. To differentiate how nucleoside recognition varie...

1. Urine nucleoside phosphorylase was purified from the vegetative cells and spores of Bacillus cereus var. terminalis. The enzymes from the vegetative cell and the spore were found to have similar physical and catalytic properties. A mutant (strain 29) with only 2% of the level of enzyme activity in the vegetative cell also had a comparably low level in the spore. 2. The vegetative cell enzyme...

متن کاملProperties of purine nucleoside phosphorylases from spores and vegetative cells of Bacillus cereus and their modification by orthophosphate.
The purine nucleoside phosphorylases (PN-phosphorylase) from spores and vegetative cells of Bacillus cereus were each purified to electrophoretic homogeneity. The turnover numbers for the spore and vegetative cell enzymes were 145 and 181 moles of inosine cleaved per mole of enzyme per set, respectively. The PN-phosphorylase from vegetative cells was more anionic than that from the spores durin...
