MF

3-isopropylmalate dehydratase activity

Catalysis of the reaction: (2R,3S)-3-isopropylmalate = (2S)-2-isopropylmalate.

GO:0005739

CC

mitochondrion

A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.

BP

leucine biosynthetic process

The chemical reactions and pathways resulting in the formation of leucine, 2-amino-4-methylpentanoic acid.

GO:0009536

CC

plastid

Any member of a family of organelles found in the cytoplasm of plants and some protists, which are membrane-bounded and contain DNA. Plant plastids develop from a common type, the proplastid.

GO:0009570

CC

chloroplast stroma

The space enclosed by the double membrane of a chloroplast but excluding the thylakoid space. It contains DNA, ribosomes and some temporary products of photosynthesis.

GO:0016836

MF

hydro-lyase activity

Catalysis of the cleavage of a carbon-oxygen bond by elimination of water.

GO:0019761

BP

glucosinolate biosynthetic process

The chemical reactions and pathways resulting in the formation of glucosinolates, substituted thioglucosides found in rapeseed products and related cruciferae.
