Subtilisin Carlsberg was modified with comb-shaped poly (ethylene glycol), PM13. PM13 modified subtilisin (PM13-Sub) could be solubilized clearly in a wide range of pure ILs, whereas native subtilisin was not soluble in any ILs. Furthermore, PM13-Sub dissolved in ILs exhibited the excellent catalytic activity in transesterification of N-acetyl-L-phenylalanine ethyl ester with 1-butanol. This markedly high activity in the IL was superior to that in organic solvents commonly used for enzymatic catalysis. PM13-Sub was also found to retain its catalytic activity in the ILs for a prolonged period.
