FIG. 1.

Schematic representation of the fragments (1 to 8) of cloned tsa genes based on the bor56 nucleotide sequences and inferred amino acid sequences (GenBank accession no. L04956). The malE sequences of expression vector pIH821 are fused to portions of the fragments corresponding to the amino terminus and are not depicted. Numbers beside the fragments refer to amino acid residues of the translated Δtsa gene.
