Abstract

Thirty-two genera of microorganisms were identified with one of six distinctive control patterns for the enzyme 3-deoxy-d-arabino-heptulosonate-7-phosphate synthetase. These patterns included sequential feedback inhibition, isoenzyme feedback inhibition, cumulative feedback inhibition, and three (apparent) simple one-effector patterns. Documentation is provided of an overwhelming tendency for control patterns to be strongly conserved among the member species of the various genera that were examined.

摘要

利用3-脱氧-D-阿拉伯庚酮糖-7-磷酸合成酶的六种独特控制模式之一,鉴定出了32个微生物属。这些模式包括顺序反馈抑制、同工酶反馈抑制、累积反馈抑制以及三种(明显的)简单单效应物模式。文中提供的资料表明,在所研究的各属成员物种中,控制模式具有极强的保守倾向。
