A methenyl tetrahydromethanopterin cyclohydrolase and a methenyl tetrahydrofolate cyclohydrolase in Methylobacterium extorquens AM1.

European journal of biochemistry - 1 Apr 1999

Abstract excerpt

Recently it was found that Methylobacterium extorquens AM1 contains both tetrahydromethanopterin (H4MPT) and tetrahydrofolate (H4F) as carriers of C1 units. In this paper we report that the aerobic methylotroph contains a methenyl H4MPT cyclohydrolase (0.9 U x mg-1 cell extract protein) and a methenyl H4F cyclohydrolase (0.23 U x mg-1). Both enzymes, which were specific for their substrates, were purified and...
