16SrDNA遺伝子の塩基配列解析を行うことにより同定を行った。16SrDNA遺伝子の塩基配列をPCRにて増幅し、シーケンス解析を行った。BLAST相同性検索のデータベースはDB-BA11.0(テクノスルガ・ラボ社)および国際塩基配列データベースを使用した。その結果、LEBP-3株はBurkhlderia属で構成されるクラスター内に含まれたが、何れの既知種とも異なる分子系統学的位置を示したことから、種名の同定に至らなかった。
Burkholderia sp.LEBP-3株の全ゲノムドラフト解析を実施した。LEBP-3株を2mLのLB培地(トリプトン10g/L、酵母エキス5g/L、塩化ナトリウム10g/L)で37℃振とう培養を実施した。培養終了後、培養液から菌体を回収し、Nucleo Spin Tissue(製品名、MACHEREY-NAGEL社製)を使用してゲノムDNAを抽出した。Burkholderia sp.LEBP-3株の全ゲノムドラフト解析およびアノテーションを実施し、7679個のオープンリーディングフレーム(Open reading frame;ORF)を同定した。この情報を元に、スクシニルCoA:アセチルCoAアシルトランスフェラーゼとしてpaaJ(L3)を、3-ヒドロキシアジピルCoAデヒドロゲナーゼとしてpaaH(L3)を、3-ヒドロキシアジピルCoAデヒドラターゼとしてpaaF(L3)を、2,3-デヒドロアジピルCoAレダクターゼとしてmmgC(L3)を同定した。
PCR断片の増幅にはPrimeSTAR Max DNA Polymerase(製品名、タカラバイオ製)、プラスミドの調製には大腸菌JM109株を用いた。塩基配列のコドン最適化には、GeneArt GeneOptinizer(ソフトウェア名、サーモフィッシャーサイエンティフィック社)、または、ユーロフィンジェノミクス社の人工遺伝子合成サービスを用いた。
