OAC1 (P32332, YKL120W) notes

• Mitochondrial carrier; reconstituted transport of malonate, oxaloacetate, sulfate, thiosulfate PMID:10428783
• Inner membrane PMID:10428783
• Exports alpha-IPM for leucine biosynthesis PMID:18682385
• oac1 leu4 synthetic leucine requirement PMID:18682385

Decisions

• All IDA rows accepted; root transporter activity IBA marked over-annotated.
• Core: GO:0034658 (alpha-IPM export) + GO:0015131, inner membrane.
• No YeastPathways reaction for OAC1 (transport step absent from LEU pathway frame); module adds it correctly.
