Effect of phosphorus supply on periplasmic protein profiles in Rhizobia

Smart, J.B., Dilworth, M.J. and Robson, A.D. (1984) Effect of phosphorus supply on periplasmic protein profiles in Rhizobia. Archives of Microbiology, 140 (2-3). pp. 287-290.

Lysozyme/EDTA treatment of four fast-growing rhizobia released repeatable protein profiles after polyacrylamide slab gel electrophoresis. Similar treatment of slow-growing rhizobia failed to release such periplasmic proteins. For the four-fast-growing rhizobia, both P-repressible and P-inducible protein bands occurred. The only P-repressible protein identified was alkaline phosphatase, which showed strain differences in both electrophoretic mobility and activation by Mg2+. The derepression of the P-repressible periplasmic proteins in cowpea Rhizobium NGR234 correlated with derepression of both phosphate and glycerol 1-phosphate uptake.
