摘 要: | PEX11基因家族成员是参与过氧化物酶体增殖调控的关键因子, 文章利用生物信息学方法对26种代表性真菌的PEX11基因家族成员进行了检索和进化分析。研究发现:(1)26种真菌中共有66个可能的PEX11p。酵母类真菌有1个或2个PEX11p, 而大多数丝状真菌中包含2到3个, 其中子囊菌中PEX11p的个数偏多, 个别种类达到5个; (2)真菌PEX11p可分为3类, 大多数真菌含有类型Ⅰ和类型Ⅲ的PEX11p, 类型Ⅱ是盘菌亚门真菌所特有的, 可能与类型Ⅰ和类型Ⅲ在功能上有冗余; (3)通过MEME分析, 发现PEX11p含有多个保守区域, 其中C末端的Motif8具有很高的保守性, 推测可能对PEX11p发挥功能具有重要作用。文章对进一步研究真菌PEX11p的进化与功能以及过氧化物酶体的增殖具有重要意义。

Abstract: | The family members of PEX11 are key factors involved in regulation of peroxisome proliferation. Sixty-six PEX11p candidates of PEX11 gene family from26 representative fungal species were obtainedand analyzed by bioinformatic strategies. In most filamentous fungi, 2 or 3 potential PEX11ps were found, in contrast with 1 or 2 in yeast species. Com-pared with other fungal species, the Ascomycetes tend to have more PEX11ps, and even 5 in several individuals. The data of phylogenetic analysis and protein structure indicated that all of the PEX11ps were divided into 3groups: I, II, and III. The members of group I and groupIIIexisted in most species, while those in group II were found only in Pezizomycotina. By MEME analysis, 5-6 conserved motifs were found in each PEX11ps. Among them,motif 8 in C-terminal had the most conservation, indicating that this motif probably plays a key role in maintaining the proper functionof PEX11p. |
