Nucleotide and deduced amino acid sequences of the gene aprX-sk37. Translation starts at position 1. The aprX-sk37 gene comprises a 1293 bp ORF encoding 431 amino acid residues, indicated as single-letters above the nucleotide sequence. The nucleotide and predicted amino acid are numbered on the right and left sides. The predicted -35 and -10 regions of the putative short and long promoters (P_S and P_L) are presented in bold. The putative ribosomal binding site (RBS) and the transcription terminator sequences are underlined. Residues involving in the hypothetical catalytic triad, Asp₁₄₀, His₁₇₈, and Ser₃₆₇, are boxed. The stop codon is indicated by an asterisk.
