Abstract
The present invention relates to a process for the enzymatic production of a dipeptide composition from a cyanophycin (CGP) or CGP-like polymer preparation by degrading the polymer preparation with an CGPase, a CGPase particularly adapted for said process, and the use of cyanophycin (CGP) or CGP-like polymers or fragments thereof, notably a dipeptide composition obtained by the process as defined above, as pharmaceutical composition, medicament, or as food or feed substitute.
Claims12
A process for the enzymatic production of a β-dipeptide composition from a preparation of a cyanophycin (CGP) or CGP-like polymer, said process comprising contacting the preparation of the CGP or CGP-like polymer with an CGPase from P. alcaligenes having a molecular weight of about 45 kDa, an optimum temperature of about 50° C. and an optimum pH range of 7 to 8.5 for enzymatic activity and having the ability to degrade CGP or CGP-like polymer into β-Asp-Arg, thereby degrading the CGP or CGP-like polymer into β-dipeptides.
