Nucleotide and predicted amino acid sequences of HK_R . (A) The nucleotide sequence of the 5′ end of cDNA is compared with that of human HK_I , ×61091.Gb_Pr.25 The predicted translation initiation site is indicated with bold letters and the in-frame stop codon is underlined. The two sequences are aligned with the FASTA program. (B) The predicted amino acid sequence of the N-terminus which differs from that of HK_I is shown. The subsequent sequence is identical to HK_I .
