Abstract

The enzyme p-hydroxyphenylpyruvate hydroxylase (HPPH) is involved in pigmentation (pyomelanin) via homogentisic acid (HGA). Pyomelanin formation is correlated with HGA production and expression of HPPH in three disparate marine species: Vibrio cholerae, a Hyphomonas strain, and Shewanella colwelliana. Induction of pigmentation in V. cholerae 569B by nutrient limitation also correlated with production of HGA.

摘要

对羟基苯丙酮酸羟化酶(HPPH)通过尿黑酸(HGA)参与色素沉着(脓黑素)过程。在三种不同的海洋物种中,即霍乱弧菌、一种生丝微菌菌株和科氏希瓦氏菌,脓黑素的形成与HGA的产生以及HPPH的表达相关。营养限制诱导霍乱弧菌569B产生色素沉着也与HGA的产生相关。
