摘要
分析了抗冻蛋白的作用机制及基因工程的研究进展.抗冻蛋白是一类具有热滞效应、冰晶形态效应和重结晶抑制效应的蛋白质.近些年的工作主要集中在该类蛋白质抗冻机制及基因工程的研究上.抗冻蛋白具有广泛的应用前景,它不但可以应用于食物的冷鲜贮存及移植器官的低温保存,还可通过转基因提高经济作物的抗冻能力.
Antifreeze proteins（AFPs） are the thermal hysteresis proteins that have the ability to modify the growth and inhibit the recrystallization of the ice.Antifreeze proteins aroused great interests of many researchers due to its special structure and functions.Recent studies are focused on their antifreeze mechanism and genetic engineering in attempts to better understand how exactly AFPs work.AFPs have wide applications.They can aid in the food storage and transplant organ cryopreservation,also by transgene they could enhance the antifreeze ability of crops.This article reviewed the recent advance in its antifreeze mechanism and genetic engineering.
