defensin

Defensin is a widely existed antimicrobial peptide in plants, insects and mammals.

防御素是一种广泛存在于动植物界的抗菌多。

Human defensins,found in the blood,intestinal tract and epithelial cells,are small,cystin-rich cationic peptides with special structure.

防御素是一种存在于血液、肠道表皮细胞中具有特殊空间结,富含精氨酸的阳离子多。

Defensin,existing in the right arm of the second chromosome of drosophila melanogaster,encodes a product which possesses an anti-bacterial peptide activity and resists Gram-positive bacteria.

由于其有牢固的分子骨架、广泛的分生物活性,对它的研究已成为当前国际研究热点。
