Is overexpressed beta-galactosidase stable at 42oC?
Another question :
In many cases, several to ten amino acid-added beta-
galactosidase at the N-terminus is biologically active.
Is there any example in which N-terminally modified 
beta-galactosidase loses its activity?

I would appreciate ur knowledge or references.
