  biliverdin-IX在人体中的尿液排泄。

  摘要：

  使用来自七个健康成年人的尿液样本研究了α-，β-，γ-和δ-胆小素-IX的四个异构体的分布和相对比例。将来自样品的联肝素吸附在滑石上，然后将吸附的联肝素浸入甲醇和浓硫酸的溶液中，以衍生为二甲基酯。将酯送入反相柱中进行纯化，然后在反相柱上通过HPLC进行定量。分析显示，在24小时尿液中的biliverdins由6.4 +/- 2.5 nmolα-和9.3 +/- 5.4 nmolβ-异构体组成。HPLC分析表明，δ-异构体的存在量要少得多，但没有检测到γ-异构体。α-和β-异构体的鉴定通过共色谱和吸收光谱进行。

  Background: Heme oxygenase catalyzes the conversion of heme to iron, carbon monoxide and biliverdin employing oxygen and reducing equivalents. This enzyme is essential for heme-iron utilization and contributes to virulence in Leptospira interrogans. Methods: A phylogenetic analysis was performed using heme oxygenases sequences from different organisms including saprophytic and pathogenic Leptospira species. L. interrogans heme oxygenase (LepHO) was cloned, overexpressed and purified. The structural and enzymatic properties of LepHO were analyzed by UV-vis spectrophotometry and (1)H NMR. Heme-degrading activity, ferrous iron release and biliverdin production were studied with different redox partners. Results: A plastidic type, high efficiently ferredoxin-NADP(+) reductase (LepFNR) provides the electrons for heme turnover by heme oxygenase in L. interrogans. This catalytic reaction does not require a ferredoxin. Moreover, LepFNR drives the heme degradation to completeness producing free iron and α-biliverdin as the final products. The phylogenetic divergence between heme oxygenases from saprophytic and pathogenic species supports the functional role of this enzyme in L. interrogans pathogenesis. Conclusions: Heme-iron scavenging by LepHO in L. interrogans requires only LepFNR as redox partner. Thus, we report a new substrate of ferredoxin-NADP(+) reductases different to ferredoxin and flavodoxin, the only recognized protein substrates of this flavoenzyme to date. The results presented here uncover a fundamental step of heme degradation in L. interrogans. General significance: Our findings contribute to understand the heme-iron utilization pathway in Leptospira. Since iron is required for pathogen survival and infectivity, heme degradation pathway may be relevant for therapeutic applications.
