[Recombinant thymosin alpha1].

An artificial gene encoding thymosin alpha1 was obtained by the chemoenzymatic synthesis and cloned into Escherichia coli. An expressing recombinant plasmid containing the hybrid protein gene, which encodes amino acid sequences of thymosin alpha1 and the Saccharomyces cerevisiae intein Sce VMA, was constructed. The expression of the hybrid protein from the resulting hybrid gene in E. coli, the properties of the resulting hybrid protein, and the conditions for its nonenzymatic cleavage to thymosin alpha1 were studied.
