== Publication Abstract from PubMed ==
Serratia sp. ATCC 39006 has two tandemly positioned genes, ser4 and ser5, both annotated as sugar aminotransferases, in a putative secondary metabolite biosynthetic gene cluster. Ser5 possesses a complete fold-type I aminotransferase fold, while Ser4 lacks the N- and C-terminal regions and a catalytically important lysine residue of fold-type I aminotransferase. We herein revealed that Ser4 and Ser5 formed a heterotetrameric complex (SerTA) with aminotransferase activity and determined the crystal structures. MD simulations and activity assays with SerTA variants indicated that residues from helix alpha-8* of inactive Ser4 are important for activity, confirming the importance of heterocomplex formation for activity. Furthermore, the structures suggest that SerTA recognizes a substrate loaded on the carrier protein.
