Abstract The Guillardia theta chloroplast hlpA gene encodes a protein resembling bacterial histone-like protein HU. This gene was cloned and overexpressed in Escherichia coli cells, and the resulting protein product, HlpA, was purified and characterized in vitro. In addition to exhibiting a general DNA-binding activity, the chloroplast HlpA protein also strongly facilitated cyclization of a short DNA fragment in the presence of T4 DNA ligase, indicating its ability to mediate very tight DNA curvatures.
