  • Patent number: 6838555
    Abstract: Disclosed are Hansenula polymorpha mutants useful as host cells through which various proteins can be produced as being intact at high yield and a process for preparing recombinant proteins using the host cells. Using various vectors, Hansenula polymorpha is made to be a mutant which is deprived of methanol assimilating ability and incapable of utilizing methanol as a carbon source. This Hansenula polymorpha mutant is used as a high yield host to produce recombinant proteins without continuous feeding of methanol, with the aid of an expression cassette carrying a promoter capable of inducing the expression at a low concentration of methanol. Further, the mutant is also lacking in carboxypeptidase Y, protease Y and/or carboxypeptidase a activity, so the recombinant protein of interest is not degraded at its carboxyl terminal when being expressed in the cell. Thus, intact recombinant protein can be obtained.
