== Function ==
[https://www.uniprot.org/uniprot/SCOT_DROME SCOT_DROME] Key enzyme for ketone body catabolism (PubMed:24100554). Transfers the CoA moiety from succinate to acetoacetate (PubMed:24100554). Formation of the enzyme-CoA intermediate proceeds via an unstable anhydride species formed between the carboxylate groups of the enzyme and substrate (By similarity).[UniProtKB:Q29551]<ref>PMID:24100554</ref>

== Publication Abstract from PubMed ==
Succinyl-CoA:3-ketoacid CoA transferase (SCOT) plays a crucial role in ketone-body metabolism. SCOT from Drosophila melanogaster (DmSCOT) was purified and crystallized. The crystal structure of DmSCOT was determined at 2.64 A resolution and belonged to space group P212121, with unit-cell parameters a = 76.638, b = 101.921, c = 122.457 A, alpha = beta = gamma = 90 degrees . Sequence alignment and structural analysis identified DmSCOT as a class I CoA transferase. Compared with Acetobacter aceti succinyl-CoA:acetate CoA transferase, DmSCOT has a different substrate-binding pocket, which may explain the difference in their substrate specificities.
