La(3+) and not Ca(2+) increases methanol dehydrogenase (MDH) activity in Methylobacterium radiotolerans NBRC15690. La(3+)- and Ca(2+)-MDH-like proteins were found to be homodimeric (α(2)) and heterotetrameric (α(2)β(2)), respectively. N-terminal amino acid sequences of these proteins revealed that La(3+)- and Ca(2+)-MDH-like proteins were encoded by xoxF and mxaFI, respectively.
镧（La(3+)）而非钙（Ca(2+)）能增加耐辐射甲基杆菌（Methylobacterium radiotolerans）NBRC15690 中的甲醇脱氢酶（MDH）的活性。La(3+)-和 Ca(2+)-MDH 样蛋白分别为同源二聚体（α(2)）和异源四聚体（α(2)β(2)）。这些蛋白的 N 端氨基酸序列表明，La(3+)-和 Ca(2+)-MDH 样蛋白分别由 xoxF 和 mxaFI 编码。
