liuC curation notes

• UniProt evidence: UniProt identifies Q88FM3 as methylglutaconyl-CoA hydratase. [file:PSEPK/liuC/liuC-uniprot.txt "SubName: Full=Methylglutaconyl-CoA hydratase"].
• A structurally characterized bacterial ortholog belongs to the 3-methylglutaconyl-CoA hydratase family, supporting the reaction-specific assignment beyond the broad crotonase fold. PMID:27271456.
• Comparative growth evidence shows that P. putida uses leucine and isovalerate. PMID:16820476.
• The same study reports that P. putida does not grow on the tested acyclic terpenes, so the electronic isoprenoid-catabolic-process annotation is removed rather than transferred from bifunctional P. aeruginosa Liu machinery. PMID:16820476.
