Abstract
Profilin (isoform I) from Acanthamoeba castellani was expressed in Escherichia coli using a bacteriophage T7-based expression vector. The recombinant material is similar to authentic profilm from Acanthamoeba-based on fluorescence monitored urea denaturation, circular dichroisrn, actin-nuoleotide exchange rate and the Ka for rabbit skeletal actin. This recombinant material crystallized from 80% saturated sodium potassium tartrate, yielding monoclinic crystals, space group C2, a = 91·4 Å, b =37·4 Å, c = 34·7 Å, α =109·6°. These crystals contain one molecule in the asymmetric unit and diffract to 2·0 Å.
