Abstract excerpt
The protein composition of natural rennet and of chromatographic and crystalline chymosin preparations has been defined by on-line reverse-phase high performance liquid chromatography/electrospray ionisation mass spectrometry (RP-HPLC/ESI-MS) and by tandem mass spectrometry (MS/MS). Natural rennet was found to consist of six chymosin species, corresponding to chymosin A and B genetic variants, each of which...
