The elongation of ovococci

Jules Philippe et al. Microb Drug Resist. 2014 Jun.

Abstract

The morphogenesis of ovococci has been reviewed extensively. Recent results have provided new insights concerning the mechanisms of elongation in ovoid bacteria. We present here the proteins involved in the elongation (firmly established and more or less hypothetical) and discuss the relationship between elongation and division of ovococci.

Topology of the elongation proteins in ovococci. The implication of MreC, MreD, PBP2b,, and RodA in elongation was experimentally shown in ovococci. The implication of PBP1a and RodZ is hypothetical.

Isolation of recombinant MreC/MreD and PBP2b/RodA complexes from pneumococcus. (A) MreC and MreD were expressed in Escherichia coli from an artificial operon fused with N-terminal Strep- and His8-tags, respectively. Membranes were isolated and solubilized with n-dodecyl-β-d-maltopyranoside. The complex was isolated by two successive affinity chromatography steps on Strep-Tactin® and Ni-NTA. (B) PBP2b with a C-terminal Strep-tag and RodA with an N-terminal His8-tag were similarly expressed and the complex isolated, in that case, first by Ni-NTA chromatography followed by a Strep-Tactin® purification. L, W, and E stand for load, wash, and elution. Samples were analyzed by Coomassie-stained sodium dodecyl sulfate–polyacrylamide gel electrophoresis.
