Abstract

The psychrotolerant bacterium Pectobacterium atrosepticum produces four N-acyl homoserine lactones under a wide range of temperatures. Their thermoregulation differs from that of the exoenzyme production, described as being under quorum-sensing control. A mechanism involved in this thermoregulation consists of controlling N-acyl homoserine lactones synthase production at a transcriptional level.

摘要

耐冷细菌黑胫果胶杆菌在广泛的温度范围内产生四种N-酰基高丝氨酸内酯。它们的温度调节与被描述为受群体感应控制的胞外酶产生的温度调节不同。这种温度调节涉及的一种机制包括在转录水平上控制N-酰基高丝氨酸内酯合酶的产生。
