昆虫触角气味结合蛋白的研究进展

Progress in the studies of antenna odorant binding proteins of insects

昆虫触角气味结合蛋白是一类亲水性的酸性蛋白 ,在触角感器淋巴液中浓度很高 ,主要分为 4种 ,即性外激素结合蛋白、普通气味结合蛋白 1、普通气味结合蛋白 2和气味结合蛋白类似蛋白。由于它们在昆虫识别外界气味物质中起着重要的作用 ,近 10年来 ,国外对其进行了广泛、深入的研究。该文从气味结合蛋白的研究方法、生化特性。

Odorant-binding proteins of insects are soluble acidic proteins,very concentrated in the lymph of chemosensory sensilla of insect antennae and belonging to four major classes(PBP,general OBP1,general OBP2 and OBP-like).Odorant-binding proteins play an important role in insect for perceiving exoteric odorant and are widely and deeply studied in the recent decade.Research methods,biochemical characteristics,molecular structure and physiological role of odorant-binding proteins are reviewed in details in this paper.
