Characterization of the His-Xyl62 and Xyl62-His enzyme activities. a The effect of different pH values on activity. b pH stability of His-Xyl62 and Xyl62-His. c The effect of different temperatures on activity. d Temperature stability of His-Xyl62. e Temperature stability of Xyl62-His. In a, b, and c, the black triangle represents His-Xyl62, and the black square represents Xyl62-His. In d, e, the black diamond represents 35 °C, the black square represents 40 °C, the black triangle represents 45 °C, the black transverse line represents 50 °C, and the black circle represents 55 °C
