Abstract
A putative indole diterpene biosynthetic gene cluster composed of eight genes was identified in a genome database of Phomopsis amygdali, and from it, biosynthetic genes of fusicoccin A were cloned and characterized. The six genes showed significant similarities to pax genes, which are essential to paxilline biosynthesis in Penicillium paxilli. Recombinants of the three putative prenyltransferase genes in the cluster were overexpressed in Escherichia coli and characterized by means of in vitro experiments. AmyG is perhaps a GGDP synthase. AmyC and AmyD were confirmed to be prenyltransferases catalyzing the transfer of GGDP to IGP and a regular di-prenylation at positions 20 and 21 of paxilline, respectively. AmyD is the first know example of an enzyme with this function. The Km values for AmyD were calculated to be 7.6 ± 0.5 μM for paxilline and 17.9 ± 1.7 μM for DMAPP at a kcat of 0.12 ± 0.003/s.
摘要:在Phomopsis amygdali的基因组数据库中发现了一个由八个基因组成的假定吲哚二萜生物合成基因簇,并从中克隆和表征了fusicoccin A的生物合成基因。这六个基因显示出与Pax基因的显著相似性,Pax基因对于青霉菌Paxillium paxilli中的Paxilline生物合成至关重要。该簇中三个假定的戊二烯基转移酶基因的重组体在大肠杆菌中过表达,并通过体外实验进行了表征。AmyG可能是GGDP合成酶。AmyC和AmyD已确认为催化将GGDP转移至IGP以及在Paxilline的第20和21位点进行常规双戊二烯基化的戊二烯基转移酶。AmyD是具有此功能的第一个已知酶的例子。AmyD的Km值计算为paxilline为7.6±0.5μM,DMAPP为17.9±1.7μM,kcat为0.12±0.003/s。

This disclosure provides peptides which have an affinity for the focal adhesion targeting (FAT) domain of focal adhesion kinase (FAK). In particular, the peptides are modified and derived from the sequence of the LD2 alpha helical domain of paxillin (e.g., LD2 peptides), the LD4 domain of paxillin (e.g., LD4 peptides), and CD8 peptides. These peptides are capable of blocking an interaction between paxillin and FAK, thereby inhibiting FAK activity related to FAK-paxillin interaction. The invention further provides uses for such peptides as therapeutics for the treatment of cancer and other diseases characterized with FAK activity and/or expression (e.g., fibrosis).
本公开提供了对焦粘附激酶(FAK)的焦粘附靶向(FAT)结构域具有亲和力的肽。具体来说,这些肽经过修改并来源于paxillin的LD2α螺旋结构域序列(例如LD2肽)、paxillin的LD4结构域(例如LD4肽)和CD8肽。这些肽能够阻断paxillin与FAK之间的相互作用,从而抑制与FAK-paxillin相互作用相关的FAK活性。该发明进一步提供了这些肽作为治疗癌症和其他具有FAK活性和/或表达(例如纤维化)特征的疾病的治疗药物的用途。
