Preliminary studies on the primary structure of rat liver dihydropteridine reductase.
Cyanogen bromide cleavage of reductively alkylated homogeneous rat liver dihydropteridine reductase afforded several peptide fragments identifiable by polyacrylamide electrophoresis of which 6 (CB-1 to CB-6) could be individually isolated by C8 reverse phase HPLC. Each was characterised by N-terminal amino acid analysis and sequence information was derived for CB-1, CB-4 and CB-6. The blocked N-terminal of the holoenzyme was identified as pyroglutamate and the C-terminal sequence was obtained by sequential degradation.
