  Purification, Characterization, Molecular Cloning, and Expression of a New Aminoacylase fromStreptomyces mobaraensisThat Can HydrolyzeN-(Middle/Long)-chain-fatty-acyl-L-amino Acids as Well asN-Short-chain-acyl-L-amino acids

  摘要：

  我们在此报告了一种新的氨酰酶的纯化、特征化、分子克隆和表达，该酶最初从放线菌Mobaraensis（Sm-AA）的上清液中分离出来。纯化的野生型Sm-AA被发现是单体蛋白，分子量为55 kDa。克隆的Sm-AA基因包含一个1,383 bp的开放阅读框（ORF），编码460个氨基酸的多肽。BLAST搜索显示，Sm-AA属于肽酶M20家族，与来自Streptomyces pristinaespiralis的假设蛋白、来自Streptomyces avermitilis的假定肽酶、来自Frankia sp.的肽酶M20、来自流感嗜血杆菌的琥珀酰二氨基庚酸去琥珀酰酶，以及来自猪肾的氨酰酶-1的同源性分别为89%、88%、67%、29%和25%。Sm-AA基因被亚克隆入表达载体pSH19，并在Streptomyces lividans TK24中表达。重组Sm-AA在S. lividans细胞中的表达量约为S. mobaraensis上清液中Sm-AA的42倍。Sm-AA对各种N-乙酰-l-氨基酸和N-(中/长)-链脂肪酰-l-氨基酸表现出高水解活性，特别偏好l-Met、l-Ala、l-Cys等的酰基衍生物，其最佳反应pH和温度约为7.5和50°C（在pH 7.5下）。

  Synthesis and evaluation of anti-tumor activities of N4 fatty acyl amino acid derivatives of 1-β-arabinofuranosylcytosine

  摘要：

  1-beta-D-Arabinofuranosylcytosine (Ara-C, Cytarabine) is one of the drugs used for acute nonlympbocytic leukemia (ANLL). However, the bioavailability of Ara-C is relatively low due to its low lipophilicity. In order to improve the lipophilicity and bioavailability of Ara-C, a series of N-4 derivatives of Ara-C, i.e., (fatty acid)-(amino acid)-Ara-C analogues, were prepared. The 15 derivatives synthesized were characterized by their melting points, optical rotations and partition coefficients. It was found that the Ara-C derivatives synthesized in this study were more lipophilic than Ara-C as determined by their partition coefficients. Their in vitro cytotoxicity and in vivo anti-tumor activity were determined and compared with that of Ara-C. It was found that the derivatives were more active than Ara-C in Hela cells, but not in HL-60 cells. The in vivo results showed that some of the derivatives were more effective than Ara-C in mice bearing S-180 tumor while others showed a decreased activity in comparison with Ara-C.
