英文摘要	The enzymatic Pictet-Spengler (PS) reaction, catalyzed by Pictet-Spenglerase (PSase), is the feature of beta-carboline (beta C) alkaloid biosynthesis. NscbB is a rare microbial PSase discovered from a cryptic beta-carboline alkaloid biosynthetic gene cluster (BGC) in the Nocardiopsis synnemataformans DSM 44143 (kidney transplant patient derived) by homologous alignment with its well-characterized counterpart McbB. The biochemical analysis showed that NscbB could catalyze L-tryptophan (K-M = 89.64 +/- 8.69 mu M) and methylglyoxal (K-M = 147.70 +/- 16.38 mu M), without cofactors, to form the two beta C skeletons 1-acetyl-3-carboxy-beta-carboline and 1-acetyl-beta-carboline in vitro. Additionally, the heterologous expression of nscbB in E. coli BL21 (DE3) revealed the efficient bioproductivity of NscbB to bioproduce two beta C skeletons, 1-acetyl-3-carboxy-beta-carboline (5.5 mg/L) and 1-acetyl-beta-carboline (3.1 mg/L), within 16 h fermentation. These results demonstrate NscbB is a novel and practical microbial PSase, which is useful for future bioactive beta C alkaloid exploitation and development.
