Task: Answer Verification
Input (English): Question: Does heme-iron utilization by Leptospira interrogans require a heme oxygenase and a plastidic-type ferredoxin-NADP ( + ) reductase?
Answer: 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.
Output (English): yes
