-Single band on SDS-gel electrophoresis (MW ~34kDa)

Figure 1. Electrophoresis analysis of BtAra43C. M, molecular weight marker (PageRuler Prestained Protein Ladder, Thermo Scientific); lane 1, BtAra43C purified from Ni sepharose fastflow column.

2. SPECIFIC ACTIVITY

1.2 U/mg protein (on pNP-α-araf) at pH 7.0 and 37℃

One Unit of pNP-α-araf activity is defined as the amount of enzyme required to release 1 μmol of glucose per minute from pNP-α-araf (5 mM) in phosphate buffer (50 mM) pH 7.0
