Updated annotation (from data): 3-methylcrotonyl-CoA carboxylase, beta subunit (EC 6.4.1.4) Rationale: Specifically important for utilizing L-Leucine. Automated validation from mutant phenotype: the predicted function (6.4.1.4) was linked to the condition via a SEED subsystem. This annotation was also checked manually. Original annotation: methylcrotonoyl-CoA carboxylase non-biotinylated subunit protein Type 1: Protein-coding gene Located on scaffold NC_003078, + strand, nucleotides 760,760 to 762,367 See nucleotide sequence around SM_b21122 or for all of scaffold NC_003078
