Nuclease S1 cleavage and the primary structure of mitochondrial DNA

Autor: Andreas Bruhn, Jürgen Koch

Publikováno v: European journal of biochemistry. 63(1)

The single-strand-specific nuclease S1 from Aspergillus oryzae rapidly converts superhelical mitochondrial DNA (African Green Monkey cells, Vero ATCC; CCL 81) into nicked circular DNA. These nicked mitochondrial DNA molecules contain two nicks, one i

4α-6α-Dihydroxy-A-homoazadiron, ein neues tetranortriterpenoid aus azadirachta indica a. juss (meliaceae)

Autor: Andreas Bruhn, Michael Bokel, Wolfgang Kraus

Publikováno v: Tetrahedron Letters. 25:3691-3692

Ether extraction of dried leaves of Azadirachta indica followed by chromatography afforded a new A-homoazadiron derivative for which structure (1) was proposed on the basis of MS, NMR, and IR data.
