sAC amino acid sequence. Predicted amino acid sequence of rat sAC. Amino acids in bold indicate presumptive catalytic domains, C1 and C2. Double-underlined amino acids correspond to sequences of tryptic peptides derived from the purified 48-kDa protein. Dotted underlined amino acids conform to a consensus P loop sequence, and underlined sequences are predicted to form a leucine zipper. Valine 469 is underlined and is the last sAC amino acid in the catalytically active heterologously expressed truncation.
