Thermostability of the re-AuFaeA and re-AuFaeAA126C-N152C.

Thermostability of (a) re-AuFaeA and (b) re-AuFaeAA126C-N152C were evaluated by incubating in the absence of substrate at temperatures ranging from 50 to 60°C for different time, respectively, and the residual enzyme activities were measured under the standard assay conditions.
