Soil microorganisms that produce the enzyme 1-aminocyclopropane-1-carboxylate (ACC) deaminase promote plant growth by sequestering and cleaving plant-produced ACC, and thereby lowering the level of ethylene in the plant. Decreased ethylene levels allows the plant to be more resistant to a wide variety of environmental stresses. Here, the biochemistry of ACC deaminase; the environmental distribution, regulation, evolution and expression of ACC deaminase genes; and information regarding the effect of this enzyme on different plants is documented and discussed.
产生1-氨基环丙烷-1-羧酸（ACC）脱氨酶的土壤微生物通过螯合和裂解植物产生的ACC来促进植物生长，从而降低植物体内的乙烯水平。乙烯水平降低使植物对多种环境胁迫更具抗性。本文记录并讨论了ACC脱氨酶的生物化学；ACC脱氨酶基因的环境分布、调控、进化和表达；以及关于这种酶对不同植物影响的信息。
