| Me.tha.no.coc.co'i.des. Gr. adj. suff. ‐oides similar to; N.L. neut. n. Methanococcoides organism similar to Methanococcus. Euryarchaeota / Methanomicrobia / Methanosarcinales / Methanosarcinaceae / Methanococcoides The genus Methanococcoides comprises four species, Methanococcoides methylutens, Methanococcoides burtonii, Methanococcoides alaskense, and Methanococcoides vulcani. Cells are irregular cocci, 0.5–3 μm in diameter, occurring singly or in pairs, and may be motile. Clumps of cells can also observed. Cells exhibit a blue‐green autofluorescence under UV illumination. The cell wall consists of a very thin protein S‐layer, approximately 10‐nm thick. Susceptible to lysis by hypotonic or detergent shock. Eurypsychrophilic to mesophilic. Strict... |

| CM-Toyopearl陽イオン交換カラムクロマトグラフィーおよびSephacryl S-200ゲルろ過カラ ムクロマトグラフィーによって、常温性菌核病菌Sclerotinia sclerotiorumの20℃培養抽出物 のポリガラクツロナーゼ活性画分からポリガラクツロナーゼⅠを単離した。ポリガラクツ ロナーゼⅠ精製標品(P4-4-2)の比活性は3 662U/mgであり、粗抽出液から全体として116倍に 精製した。精製標品はポリアクリルアミドゲル電気泳動によって、均一であることが示さ れた。また、SDS存在下ポリアクリルアミドゲル電気泳動によって本酵素の分子質量は 39.8±1.10kDa(S.E.)、さらに等電点電気泳動によって本酵素の等電点はpH8.70と見積もられた。 Polygaracturonasehas been isolated from the mesophilic white mold Sclerotinia Sclerotiorum by cation-exchange chromatography on a column of CM-Toyopearl followed by gel filtration on a column of Sephacryl S-200. Purified enzyme preparation(P4-4-2) had a specific activity of 3 662 units per mg of protein, that is, 116-fold purification over the crude extract of the wheat bran culture of the mesophilic fungus S.... |
