  烟酰胺酶的表征：稳态动力学参数、烟碱醛类的抑制作用和催化机制

  摘要：

  烟酰胺酶是将烟酰胺水解为烟酸的代谢酶。这些酶在生物学中广泛分布，例如在分枝杆菌、古细菌、真细菌、原生动物、酵母和无脊椎动物的基因组中发现了编码，但在哺乳动物中没有发现。尽管最近的结构工作提高了我们对这些酶的理解，但它们的催化机制仍不清楚。最近的数据表明，烟酰胺酶是几种病原微生物的生长和毒力所必需的。Saccharomyces cerevisiae、Drosophila melanogaster和Caenorhabditis elegans的酶调节它们各自生物体的寿命，这与 NAD +调节中提出的作用一致新陈代谢和机体衰老。在这项工作中，来自C. elegans , Sa.的烟酰胺酶的稳态动力学参数。据报道，酿酒酵母、肺炎链球菌（一种导致人类肺炎的病原体）、伯氏疏螺旋体（导致莱姆病的病原体）和恶性疟原虫（对大多数人类疟疾负责）。烟酰胺酶通常是具有稳态k cat值通常超过1 s -1 的有效催化剂。该ķ米烟酰胺的值很低，在
