Schematic representation of the abbreviations
used to describe the various forms of AC derived by mixing the
cytosolic C1 or C1a or chimeric C1 regions with C2 domains of either
ACV or ACI. The various domains of ACI (black) and ACV (white) are
represented in the boxes. The amino acid residues encompassing the
domains in bovine ACI are as follows: C1, 236–607; C1a, 236–471; C1b,
472–607; C2, 809–1,133. In canine ACV, the domains shown comprise the
following amino acid residues: C1, 322–683; C1a, 322–571; C2,
933–1,184. In the list of abbreviations, the roman numeral preceding
the C1 or C2 domains and their subregions denote the AC isoform from
which that particular region is derived.
