Abstract
Description
본 발명은 송이버섯의 페닐알라닌 암모니아리아제 유전자 및 신나모일-코에이 리덕타제 유전자에 관한 것이다.The present invention relates to the phenylalanine ammoniaase gene and cinnamoyl-CoA reductase gene of Matsutake mushroom.
송이버섯의 향기성분에 대한 연구는 특허 10-0769652에 의하면 성분으로는 유리아미노산 27종, 에르고스테롤(ergosterol), 미량 금속 원소 13종, 비타민 B1, B2, C, D 및 니아신(niacin), 글리세롤(glycerol), 만니톨(mannitol), 트레할로즈(trehalose), 포도당 셀룰로오스(glucose cellulose), 헤미셀룰로오스(hemicellulose), 키틴(chitin), 펙틴 리그닌(pectin lignin), 5´-AMP, 5´-CMP, 5´-GMP, 5´-UMP, 1-옥텐-3-올(1-octene-3-ol), 메틸 시나메이트(methyl cinnamate), 에미타민(emitamin), 산성 포스포디에스테라아제(phosphodiesterase)등이 알려져 있다. 이 중 메틸신나메이트는 신남산에 메틸기가 결합된 것으로서 이와 유사한 형태의 신남산 알데히드가 송이버섯의 주요 향기 성분으로 인식되어 있다.According to patent 10-0769652, the odor component of pine mushrooms includes 27 free amino acids, ergosterol, 13 trace metal elements, vitamins B1, B2, C, D and niacin and glycerol. (glycerol), mannitol, trehalose, glucose cellulose, hemicellulose, chitin, pectin lignin, 5´-AMP, 5´-CMP, 5´-GMP, 5´-UMP, 1-octene-3-ol, methyl cinnamate, emitamin, acid phosphodiesterase Known. Among these, methyl cinnamate is a methyl group bonded to cinnamic acid, and a similar form of cinnamic acid aldehyde is recognized as a main scent component of pine mushroom.
한편 페닐알라닌에서 트랜스신남산이 되는데 이때에 관여하는 효소가 페닐알라닌 암모니아 리아제이다. 트랜스신남산에서 분지되어 파라큐마린산이 되어 플라보노이드, 스코포린, 리그닌, 시린진 그리고 레스베라트롤 등이 생합성 되는 것으로 알려져 있다 (ref). 트랜스신남산의 한 분지는 신나모일-코에이로 되며 여기서 다시 피노실빈이나 신남알데하이드가 되는데 신남알데하이드로 되는 과정에 관여하는 효소가 신나모일-코에이 리덕타제이다. 따라서 페닐알라닌 암모니아리아제와 신나모일-코에이 리덕타제는 송이버섯의 향기에 주요성분인 신남알데하이드의 생성에 주요한 두 가지의 효소이다.On the other hand, from phenylalanine to transcinnamic acid, the enzyme involved in this is phenylalanine ammonia lyase. It is known to be branched from transcinnamic acid to paracumarin acid to biosynthesize flavonoids, scoporin, lignin, sirin and resveratrol (ref). One branch of transcinnamic acid is cinnamoyl-coei, where it becomes pinocylbin or cinnamic aldehyde, and the enzyme involved in the process of cinnamic aldehyde is cinnamoyl-coei reductase. Thus, phenylalanine ammonia lyase and cinnamoyl-CoA reductase are two major enzymes in the production of cinnamic aldehyde, which is a major component of the scent of pine mushroom.
그러나, 상기한 연구 보고들에서 송이버섯의 향기에 대한 물질이나 이의 복합물 또는 유전자 수준에 대한 연구는 전혀 보고된 바 없다.However, there have been no reports on the substance, complex or gene level of pine mushroom scent in the above mentioned studies.

또한, 본 발명은 서열번호 2로 표시되는 DNA 염기서열을 제공하는 것을 특징으로 한다.In addition, the present invention is characterized by providing a DNA base sequence represented by SEQ ID NO: 2.
이상에서 상술한 바와 같이, 본 발명은 송이버섯의 페닐알라닌 암모니아리아제(phenylalanine ammonia lyase) 유전자 및 신나모일-코에이 리덕타제(cinnamoyl-CoA reductase) 유전자를 제공하는 효과가 있다.As described above, the present invention has an effect of providing a phenylalanine ammonia lyase gene and a cinnamoyl-CoA reductase gene of Matsutake mushroom.

The primary cDNA was PCR again as a template to make a final cDNA, inserted into a vector, and electroporated the resulting cDNA library. Sequencing each clone using the Seq I sequencing primer and blast search the results in NCBI to obtain high homology with the phenylalanine ammonia lyase and cinnamoyl-CoA reductase genes.
