Abstract: The small nanH gene encoding the neuraminidase from Clostridium perfringens ATCC 10543 was cloned in JM109 using pUC19 as a vector. Sequence analysis revealed an ORF encoding 382 amino acids without a signal peptide sequence. Four regions of amino-acid sequence, 71-82, 140-151, 208-219, and 255-266 constituted four repeated and conserved sequence motifs-Ser-X-Asp-X-Gly-X-Thr-Trp-, the "Asp boxes." When compared, the nanH polypeptides of C. perfringens ATCC 10543 and Salmonella typhimurium LT12 shared 33% seque…
