Injection of Escherichia coli into larvae of the coleopteran Holotrichia diomphalia results in the appearance of antibacterial activity in the hemolymph. An antibacterial protein, named holotricin 2, was purified from larvae of this insect and characterized. A cDNA clone for holotricin 2 was isolated and its complete sequence was determined. This protein was found to inhibit the growth of Gram-negative bacteria and to consist of 72-amino acid residues with no cysteine residues. Its amino acid… CONTINUE READING
