FIG. 1.

Nucleotide sequence of the M. morganii PhoC acid phosphatase gene and predicted amino acid sequence. A 747-bp ORF is shown with the deduced 249-amino-acid sequence. Sequences confirmed by protein sequencing are underlined. The signal sequence of the PhoC protein is doubly underlined. The amino acid residues substituted in the course of random mutagenesis are shaded in black. The mutagenic primer is indicated by an arrow. Three phosphatase motif domains are indicated in boxes under the deduced amino acid sequence.
