The survival of washed suspensions of Mycoplasma.
Washed Mycoplasma organisms died rapidly when suspended in 0435 yo (w/v) NaCl prepared in laboratory ‘distilled’ water (steam condensate) at room temperature; this rapid killing was decreased by adding to the suspensions certain chelating agents, reducing agents or finely ground manganese dioxide. Washed organisms survived well in potassium phosphate (K,HPO,, 0.01 M adjusted to pH 7) dissolved ...
متن کاملSubstrate specificity of citrate lyase deacetylase of Rhodopseudomonas gelatinosa and Rhodopseudomonas palustris.
Citrate lyase (EC 4.1.3.6) isolated from Rhodopseudomonas palustris was investigated with regard to its kinetic properties and its subunit composition. This enzyme was inactivated by citrate lyase deacetylase (EC 3.1.2.-) of Rhodopseudomonas gelatinosa. A corresponding cross-reaction was measured with partially purified deacetylase of R. palustris and citrate lyase of R. gelatinosa. The three d...
متن کاملCrystallization and subunit composition of citrate lyase of Rhodopseudomonas gelatinosa.
Previously, a purification procedure for citrate lyase (EC 4.1.3.6) of Rhodopseudomonas gelathosa has been described [l] which because of the instability of the enzyme in some purification steps and of the low yields is not suited for the preparation of large amounts of citrate lyase. In connection with studies on the enzymes which modify citrate lyase by acetylation or deacetylation [2,3] it w...
متن کاملThe photosynthetic metabolism of acetone by Rhodopseudomonas gelatinosa.
acetol was an intermediate in the metabolism of acetone by an unidentified soil diphtheroid. Because of the divergence of these results from those previously reported for R. gelatinosa, the photosynthetic metaboljsm of acetone was reinvestigated by means of a more direct approach. In addition to the two pathways indicated above, a third variation is postulated in which cleavage of acetone to CZ...
متن کاملFormation of Bacitracin by Washed Cell Suspensions of Bacillus Licheniformis.
Although the microbial formation of a variety of polypeptides possessing antibiotic activities has been known for some time, the biosynthesis of these compounds has as yet received little attention. Not only is the mechatnism of formation of these biologically active compounds of interest in itself, but the biosyntheses of these polypeptides are potential systems for investigating the general p...
