The complete amino acid sequence of the mature form of rat sepiapterin reductase.
The partial amino acid sequence of rat sepiapterin reductase was determined using peptides generated by cleavage of the S-carboxyamidomethylated protein with Achromobacter protease I, cyanogen bromide, chymotrypsin or BNPS-skatole. The protein began with N-acetyl methionyl residue at the N-terminus and ended with isoleucyl residue at the C-terminus. The present results essentially coincided with the amino acid sequence predicted from the nucleotide sequence of the cDNA recently reported by Citron et al. (Proc. Natl. Acad. Sci. USA 87, 6436-6440 (1990)), clarified the processing event during the biosynthesis and provided the complete amino acid sequence of the mature form of the enzyme.
