在未饲养和养殖的非洲肺鱼中，尿素合成速率和鸟氨酸-尿素循环酶的活性相似。在非洲爪蟾（Xenopus laevis）中，当尿素生物合成速率降低时，饥饿感降低；当尿素生物合成速率增加时，在0.9%盐水或湿泥炭中维持时，磷酸氨基苯合成酶活性升高。鸟氨酸-尿素循环酶的活性可以指示尿发生的速度。
The rate of urea synthesis and the activity of ornithine-urea cycle enzymes were similar in unfed and estivating African lungfish [Protopterus aethiopicus]. In Xenopus laevis, car-bamyl phosphate synthetase activity decreased following starvation when the rate of urea biosynthesis decreases, and increased during maintenance in 0.9% saline or moist peat when urea biosynthesis increases. The activity of ornithine-urea cycle enzymes may be indicative of the rate of urogenesis.
