An open reading frame coding for mannanase predicted from the partial genomic sequence of Paenibacillus woosongensis was cloned into Escherichia coli by polymerase chain reaction amplification, and completely sequenced. This mannanase gene, designated man26AT, consisted of 3,162 nucleotides encoding...

mannanase가 사용되는 분야는 무엇인가? | β-1,4-Mannanase (mannanase)는 mannose간의 β-1,4-mannosyl 결합을 무작위적으로 분해하는 효소로 mannan 다당류의 분해에 중요한 역할을 한다. 그러므로 mannanase는mannan 다당류를 함유한 식물자원을 여러가지 용도로 활용하는데 필요한 효소로 알려져 있으며, 기능성 올리고당 제조,목재 펄프 가공, 바이오매스 자원의 당화 등의 목적이나 사료첨가용 효소로 사용되고 있다[15, 19, 20]. | |
Mannan 다당류의 구분 방법은 무엇인가? | Mannan 다당류는 구성성분에 따라 mannan, glucomannan,galactomannan과 galactoglucomannan으로 구별된다. Mannan은mannose 잔기가 β-1,4 결합으로 이루어져 있으며 상아 야자나 커피 종자의 배유에 존재하고, glucomannan은 mannose와 함께 glucose 잔기가 β-1,4 결합으로 포함되어 있으며 식물의 구근이나 괴경에 많고 konjac glucomannan이 잘 알려져 있다. | |
Paenibacillus 속 균주가 생산하는 효소는 무엇인가? | Paenibacillus는 포자를 형성하는 세균이며 식물성장을 촉진하는 근권세균, 항균제 생산균, 유용효소 생산균 뿐 아니라 병원성 균으로 다양한 환경에서 분리되었다[7]. Paenibacillus속 균주가 생산하는 효소로 xylanase, cellulase, pectinase, chitinase와같은 고분자 물질 가수분해 효소와 α-galactosidase,β-galactosidase를 포함한 glycosidase가 다수 보고되었다. 특히 P. |
