Figure 3. — Homodimers of PFAM architecture (PALP). (A) A cluster of interfaces present in 37 CFs and 109 PDB entries (only one structure per CF is shown). These structures include cysteine synthase, tryptophan synthase alpha subunit, threonine synthase, cystathionine beta synthase, 1-aminocyclopropane-1-carboxylate deaminase and O-acetylserine sulfhydrylase from 18 different species. (B) A cluster of interfaces present in 13 CFs and 17 PDB entries. These proteins include catabolic threonine dehydratase, serine racemase, threonine deaminase, l-serine dehydratase and two uncharacterized proteins from Schizosaccharomyces pombe. Chains are colored from blue to red from N to C terminus, respectively. Chains were aligned with Pymol to one representative structure.
