Description：β-防御素作為抗菌肽的一種,是一類富含精氨酸的陽離子的環(huán)狀多肽，序列中含有41個氨基酸，并且?guī)в腥龑Χ蜴I，廣泛分布于動物、植物和昆蟲體內(nèi)。體外抑菌試驗表明,防御素能對革蘭氏陽性和陰性細(xì)菌、真菌、分枝桿菌、螺旋體、披膜病毒等病原微生物產(chǎn)生較強(qiáng)的殺傷作用，甚至對支原體、衣原體、螺旋體以及一些惡性細(xì)胞(如腫瘤細(xì)胞)和艾滋病病毒也具有殺傷作用。運(yùn)用基因工程技術(shù)表達(dá)而大量生產(chǎn)的防御素?zé)o毒副作用，也不會使病原微生物菌株變異而產(chǎn)生抗藥性,且具有廣泛的抗性譜。β-Defensin 2 (human)由41個氨基酸組成，序列中有6個半胱氨酸，并且在自然條件下隨機(jī)形成二硫鍵，結(jié)構(gòu)相對穩(wěn)定。
β- As a kind of antibacterial peptide, defensin is a kind of cyclic peptide rich in arginine cation. It contains 41 amino acids in its sequence and has three pairs of disulfide bonds. It is widely distributed in animals, plants and insects. In vitro bacteriostasis test shows that defensin can have a strong killing effect on gram-positive and negative bacteria, fungi, mycobacteria, spirochetes, drape virus and other pathogenic microorganisms, even against mycoplasma, chlamydia, spirochetes, some malignant cells (such as tumor cells) and AIDS virus. The defensin, which are expressed by genetic engineering technology and produced in large quantities, have no side effects and will not cause the variation of pathogenic microorganism strains to produce drug resistance, and have a broad resistance spectrum. β- Defensin 2 (human) is composed of 41 amino acids, with 6 cysteine in the sequence, and randomly forms disulfide bonds under natural conditions, with a relatively stable structure.
