Fig. 3.

DNA sequence and deduced amino acid sequence of the L/B/K ALP cDNA. Numbers preceded by + or–refer to amino acid positions. All other numbers refer to nucleotide positions. Asterisks occur at 10-base intervals. Amino acids -17 to -1 comprise a putative signal peptide. A vertical line precedes amino acid +1, the amino-terminal residue found in the mature protein. Amino acid residues that have been determined by protein sequence analysis of purified liver ALP are underlined. Five potential N-linked glycosylation signals, Asn-Xaa-Thr/Ser, are boxed. A 12-bp direct repeat in the 3′ untranslated region of the cDNA is labeled by arrows. A single poly(A) addition signal AATAAA is underlined twice [10]
