ABSTRACT The Methanococcus jannaschii gene MJ1392 was cloned, and its protein product was hyperexpressed in Escherichia coli. The resulting protein was purified and shown to catalyze the condensation of pyruvate and acetyl coenzyme A, with the formation of (R)-citramalate. Thus, this gene (cimA) encodes an (R)-citramalate synthase (CimA). This is the first identification of this enzyme, which is likely involved in the biosynthesis of isoleucine. 
Isoleucine Biosynthesis in Leptospira interrogans Serotype lai Strain 56601 Proceeds via a Threonine-Independent Pathway
The existence of a leucine-like pathway for isoleucine biosynthesis in L. interrogans under physiological conditions was unequivocally proven and the similarity of this metabolic pathway in leptospires and archaea is consistent with the evolutionarily primitive status of the eubacterial spirochetes.

Enzymes of the citramalate cycle in Rhodospirillum rubrum
This work has demonstrated the presence of all the key enzymes of this cycle of acetate assimilation in R. rubrum and synthesizes crotonyl-CoA carboxylase/reductase, which is the key enzyme of ethylmalonyl- CoA pathway discovered recently in Rhodobacter sphaeroides.
Elucidation of methanogenic coenzyme biosyntheses: from spectroscopy to genomics.
This review describes pathways for the biosynthesis of methanofuran, 5,6,7,8-tetrahydromethanopterin, coenzyme F420, coENzyme M (2-mercaptoethanesulfonic acid) and coen enzyme B (7-mer Captoheptanoyl-L-threonine phosphate).
Enzymology and Evolution of the Pyruvate Pathway to 2-Oxobutyrate in Methanocaldococcus jannaschii
P phylogenetic analysis suggests that the pyruvate pathway to 2-oxobutyrate (an alternative to threonine dehydratase in isoleucine biosynthesis) evolved several times in bacteria and archaea.
Re-Citrate Synthase from Clostridium kluyveri Is Phylogenetically Related to Homocitrate Synthase and Isopropylmalate Synthase Rather Than to Si-Citrate Synthase
It is reported here that Re-citrate synthase from C. kluyveri is the product of a gene predicted to encode isopropylmalate synthase, which explains why cell extracts of the organism always exhibit some Si-citrates synthase activity.
Directed Evolution of Methanococcus jannaschii Citramalate Synthase for Biosynthesis of 1-Propanol and 1-Butanol by Escherichia coli
This work demonstrates the first production of 1-propanol and 1-butanol using the citramalate pathway and the benefit of the 2-keto acid pathway that enables a growth-based evolutionary strategy to improve the production of non-growth-related products.
Alternative isoleucine synthesis pathway in cyanobacterial species.
Cyanothece sp. ATCC 51142 is an aerobic N(2)-fixing and hydrogen-producing cyanobacterium. Isotopomer analysis of its amino acids revealed an identical labelling profile for leucine and isoleucine
Insights into the Autotrophic CO2 Fixation Pathway of the Archaeon Ignicoccus hospitalis: Comprehensive Analysis of the Central Carbon Metabolism
A comprehensive analysis of the central carbon metabolism of I. hospitalis revealed further evidence for the unexpected and unexplored diversity of metabolic pathways within the (hyperthermophilic) archaea.
Elucidation of an Alternate Isoleucine Biosynthesis Pathway in Geobacter sulfurreducens
ABSTRACT The central metabolic model for Geobacter sulfurreducens included a single pathway for the biosynthesis of isoleucine that was analogous to that of Escherichia coli, in which the isoleucine


Purification of the Azotobacter vinelandii nifV-encoded homocitrate synthase
The nifV gene product (NifV) from Azotobacter vinelandii was recombinantly expressed at high levels in Escherichia coli and purified and will also catalyze the condensation of acetyl-CoA and certain other keto acids.

Amino Acid Biosynthesis in the Spirochete Leptospira: Evidence for a Novel Pathway of Isoleucine Biosynthesis
Radioactive carbon dioxide was incubated with growing cells of Leptospira interrogans serotypes semaranga and tarassovi, and the specific activities and distribution of the label within the cellular amino acids were determined, finding the origins of the carbon skeletons were found to be consistent with known biosynthetic pathways for these amino acids.
Physiological roles of two enzymes with fumarase activity in two Pseudomonads.
The results suggest that mesaconase is not an enzyme involved in the metabolism of C5-branched-chain dicarboxylates but presumably, taking the place of fumarase, plays a role in the operation of the tricar boxylic acid cycle in the cells grown in the medium containing Fe2+ ions more than 10 nmol/ml.

Acetate and CO2 assimilation by Methanothrix concilii
The metabolic properties of Methanothrix concilii are closely related to those of Methanosarcina barkeri, and the origin of carbon atoms in glutamate, proline, and arginine showed that an incomplete tricarboxylic acid cycle operating in the oxidative direction was used for their biosynthesis.
