Small, heat-stable, DNA-binding proteins from Caulobacter crescentus.
From a heterogenous cell population of Caulobacter crescentus a deoxyribonucleoprotein fraction (DNP) was obtained by the modified technique of Sjåstad et al. (1982). Under the electron microscope DNP had a smooth fibrillar structure. The chemical properties of the proteins associated with the DNA were similar to those of other bacteria. An abundant, heat-stable, basic and DNA-binding protein, termed HCc, which has a molecular weight of 13.4 kD may be an analogue of the HU-histone-like protein from Escherichia coli.
