  Glucosinolate biosynthesis: demonstration and characterization of the condensing enzyme of the chain elongation cycle in Eruca sativa

  摘要：

  Glucosinolates are a group of sulfur-rich thioglucoside natural products common in the Brassicaceae and related plant families. The first phase in the formation of many glucosinolates involves the chain extension of the amino acid methionine. Additional methylene groups are inserted into the side chain of methionine by a three-step elongation cycle involving 2-oxo acid intermediates. This investigation demonstrated the first step of this chain elongation cycle in a partially-purified preparation from arugula (Eruca sativa). The 2-oxo acid derived from methionine, 4-methylthio-2-oxobutanoic acid, was shown to condense with acetyl-CoA to form 2-(2'-methylthioethyl)malate. The catalyst, designated as a 2-(omega-methylthioalkyl)malate synthase, belongs to a family of enzymes that mediate the condensation of acyl-CoAs with 2-oxo acids, including citrate synthase of the citric acid cycle, and 2-iso-propylmalate synthase of leucine biosynthesis. The 2-(omega-methylthioalkyl)malate synthase studied here shares properties with other enzymes of this class, but appears chromatographically distinct and is found only in extracts of plant species producing glucosinolates from chain-elongated methionine derivatives. Although the principal glucosinolates of arugula are formed from methionine that has undergone two rounds of chain elongation to form dihomomethionine, studies with substrates and substrate analogs of different chain lengths showed that the isolated enzyme is responsible only for the condensation step of the first round of elongation.

  state. The intramolecular oxidation of ketone 6 showed the preference for a tertiary delta C-H bond over a secondary one. This intramolecular oxidation method can be extended to the oxidation of the tertiary gamma' C-H bond of ketones 9 and 10. For ketone 11 with two delta C-H bonds and one gamma' C-H bond linked respectively by a sp(3) hydrocarbon tether and a sp(2) ester tether, the oxidation took place

  我们发现，从酮1-6和Oxone原位生成的二恶英类化合物在酮的δ位点发生未活化的CH键的分子内氧化，从而产生四氢吡喃。从氧化产物1a和2a的反式/顺式比率以及在酮5的δ位点处的构型的保留，我们提出氧化反应在螺环过渡态下通过一致的途径进行。酮6的分子内氧化显示，与叔键相比，叔键CH键更为优先。这种分子内氧化方法可以扩展到酮9和10的叔γ'CH键的氧化。对于具有两个δCH键和一个γ'CH键分别通过sp（3）烃系链和一个sp连接的酮11 （2）酯链，氧化仅在δCH键上发生。最后，通过引入合适的系链，已在C-17，C-16，C-3和C-5位置实现了甾族酮12-14的区域选择性羟基化。
