Description, Abstract, or Artist's Statement
This project is part of the Meiothermus ruber genome analysis project, which uses the bioinformatics tools associated with the Guiding Education through Novel Investigation – Annotation Collaboration Toolkit (GENI-ACT) to predict gene function. We investigated the biological function of the genes Mrub_1907 and Mrub_1844. We predict that Mrub__1907 encodes the enzyme ketol-acid reductoisomerase (DNA coordinates 1966630..1967649 on the reverse strand), which is the fourth step of the L-isoleucine pathway (from threonine) (KEGG map number 00290). It catalyzes the conversion of (R)-3- Hydroxy-3-methyl-2-oxopentanoate to (R)-2-3 Dihydroxy-3-methylpentanoate. The E. coli K12 MG1655 ortholog is predicted to be b3774, which has the gene identifier ilvC. We predict that Mrub__1844 encodes the enzyme dihydroxy-acid dehydratase (DNA coordinates 1901362..1903026) on the reverse strand), which is the fifth step of the L-isoleucine pathway (from threonine) (KEGG map number 00290). It catalyzes the conversion of (R)-2-3 Dihydroxy-3-methylpentanoate to (S)-3-Methyl-2-oxopentanoate. The E. coli K12 MG1655 ortholog is predicted to be b3771, which has the gene identifier ilvD.
