1-188 2.44e-114

3-isopropylmalate dehydratase, small subunit; Homoaconitase, aconitase, and 3-isopropylmalate dehydratase have similar overall structures. All are dehydratases (EC 4.2.1.-) and bind a Fe-4S iron-sulfur cluster. 3-isopropylmalate dehydratase is split into large (leuC) and small (leuD) chains in eubacteria. Several pairs of archaeal proteins resemble the leuC and leuD pair in length and sequence but even more closely resemble the respective domains of homoaconitase, and their identity is uncertain. The candidate archaeal leuD proteins are not included in the seed alignment for this model and score below the trusted cutoff. [Amino acid biosynthesis, Pyruvate family]

14-147 3.10e-42

Aconatase-like swivel domain of 3-isopropylmalate dehydratase and related uncharacterized proteins. 3-isopropylmalate dehydratase catalyzes the isomerization between 2-isopropylmalate and 3-isopropylmalate, via the formation of 2-isopropylmaleate 3-isopropylmalate. IPMI is involved in fungal and bacterial leucine biosynthesis and is also found in eukaryotes. This is the aconitase-like swivel domain, which is believed to undergo swivelling conformational change in the enzyme mechanism.

14-147 3.10e-42

Aconatase-like swivel domain of 3-isopropylmalate dehydratase and related uncharacterized proteins. 3-isopropylmalate dehydratase catalyzes the isomerization between 2-isopropylmalate and 3-isopropylmalate, via the formation of 2-isopropylmaleate 3-isopropylmalate. IPMI is involved in fungal and bacterial leucine biosynthesis and is also found in eukaryotes. This is the aconitase-like swivel domain, which is believed to undergo swivelling conformational change in the enzyme mechanism.

18-160 1.24e-26

3-isopropylmalate dehydratase, small subunit; Homoaconitase, aconitase, and 3-isopropylmalate dehydratase have similar overall structures. All are dehydratases (EC 4.2.1.-) and bind a Fe-4S iron-sulfur cluster. 3-isopropylmalate dehydratase is split into large (leuC) and small (leuD) chains in eubacteria. Several pairs of archaeal proteins resemble the leuC and leuD pair in length and sequence but even more closely resemble the respective domains of homoaconitase, and their identity is uncertain. The members of the seed for this model are those sequences which are gene clustered with other genes involved in leucine biosynthesis and include some archaea.

3-isopropylmalate dehydratase, small subunit; This subfamily is most closely related to the 3-isopropylmalate dehydratase, small subunits which form TIGR00171. This subfamily includes the members of TIGR02084 which are gene clustered with other genes of leucine biosynthesis. The rest of the subfamily includes mainly archaeal species which exhibit two hits to this model. In these cases it is possible that one or the other of the hits does not have a 3-isopropylmalate dehydratase activity but rather one of the other related aconitase-like activities.

Aconitase swivel domain. Aconitase (aconitate hydratase) catalyzes the reversible isomerization of citrate and isocitrate as part of the TCA cycle. This is the aconitase swivel domain, which undergoes swivelling conformational change in the enzyme mechanism. The aconitase family contains the following proteins: - Iron-responsive element binding protein (IRE-BP). IRE-BP is a cytosolic protein that binds to iron-responsive elements (IREs). IREs are stem-loop structures found in the 5'UTR of ferritin, and delta aminolevulinic acid synthase mRNAs, and in the 3'UTR of transferrin receptor mRNA. IRE-BP also express aconitase activity. - 3-isopropylmalate dehydratase (isopropylmalate isomerase), the enzyme that catalyzes the second step in the biosynthesis of leucine. - Homoaconitase (homoaconitate hydratase), an enzyme that participates in the alpha-aminoadipate pathway of lysine biosynthesis and that converts cis-homoaconitate into homoisocitric acid.

Bacterial Aconitase-like swivel domain. Aconitase (aconitate hydratase or citrate hydrolyase) catalyzes the reversible isomerization of citrate and isocitrate as part of the TCA cycle. Cis-aconitate is formed as an intermediate product during the course of the reaction. This is the aconitase-like swivel domain, which is believed to undergo swivelling conformational change in the enzyme mechanism. This distinct subfamily is found only in bacteria and archea. Its exact characteristics are not known.

Homoaconitase swivel domain. This family includes homoaconitase and other uncharacterized proteins of the Aconitase family. Homoaconitase is part of an unusual lysine biosynthesis pathway found only in filamentous fungi, in which lysine is synthesized via the alpha-aminoadipate pathway. In this pathway, homoaconitase catalyzes the conversion of cis-homoaconitic acid into homoisocitric acid. The reaction mechanism is believed to be similar to that of other aconitases. This is the swivel domain, which is believed to undergo swivelling conformational change in the enzyme mechanism.

Mitochondrial aconitase A swivel domain. Aconitase (also known as aconitate hydratase and citrate hydro-lyase) catalyzes the reversible isomerization of citrate and isocitrate as part of the TCA cycle. This is the aconitase swivel domain, which undergoes swivelling conformational change in the enzyme mechanism. In eukaryotes two isozymes of aconitase are known to exist: one found in the mitochondrial matrix and the other found in the cytoplasm. This is the mitochondrial form. The mitochondrial product is coded by a nuclear gene. Most members of this subfamily are mitochondrial but there are some bacterial members.
