Involved in both the tricarboxylic acid (TCA) and methylcitric acid cycles (PubMed:28956599). Catalyzes the reversible isomerization of citrate to isocitrate via cis-aconitate (PubMed:3110133, PubMed:23354745). Also catalyzes the rehydration of 2-methyl-cis-aconitate to produce 2-methylisocitrate (PubMed:28956599). The apo form of AcnA functions as a RNA-binding regulatory protein which plays a role in the regulation of citrate concentration and in the sporulation. To prevent the accumulation of excessive levels of citrate, it binds near the 5' end of the citZ mRNA, decreasing its stability and thereby limiting the concentration of citrate synthase in the cell. Aconitase also binds to the gerE transcript late in sporulation and stabilizes it for translation, thereby increasing the rate and level of GerE protein accumulation (PubMed:10468622, PubMed:16923907, PubMed:23354745, PubMed:9393699).6 Publications

Miscellaneous

Whether aconitase is active as an enzyme or an RNA-binding protein is determined by the status of an iron-sulfur (4Fe-4S) cluster that is essential for the catalytic activity of all aconitases. Citrate is both cotransported with iron and a chelator of divalent cations, including iron. If the intracellular citrate level becomes excessive, iron will be sequestered away from iron-containing proteins, including aconitase. Since excess citrate greatly stimulates aconitase synthesis via the positive regulatory effect of CcpC, the cell will gain the ability to metabolize citrate at a higher rate. If so much iron has been sequestered that aconitase loses enzymatic activity, the cell will acquire a high concentration of enzymatically inactive but RNA-binding-competent aconitase molecules. These aconitase proteins can bind to the citZ mRNA and reduce the rate of citrate accumulation by restricting the synthesis of citrate synthase protein.2 Publications

By citrate via CcpC. When citrate is absent, CcpC binds to the sites near the citB promoter and blocks expression. When citrate is present, it causes a change in the interaction of CcpC with its binding sites, resulting in derepression of citB. When citrate is very abundant, CcpC activates citB expression, presumably reflecting a change in the interaction of CcpC with RNA polymerase. Also induced by decoyinine and nutrient depletion.1 Publication

Mutagenesis of different positions (F662L, R741F, Q745E, I810T and V853A) on the C-terminal region of citB gene product shows that even B.subtilis mutant has high aconitase catalytic activity, it is defective in sporulation. The defect is at a late stage of sporulation, specifically affecting expression of sigma-K-dependent genes, many of which are important for spore coat assembly and require transcriptional activation by GerE. It strongly suggests that aconitase RNA binding activity may stabilize gerE mRNA in order to allow efficient GerE synthesis and proper timing of spore coat assembly.1 Publication

<p>This subsection of the 'Entry information' section provides a mnemonic identifier for a UniProtKB entry, but it is not a stable identifier. Each reviewed entry is assigned a unique entry name upon integration into UniProtKB/Swiss-Prot.<p><a href='/help/entry_name' target='_top'>More...</a></p>Entry nameiACNA_BACSU
<p>This subsection of the 'Entry information' section provides one or more accession number(s). These are stable identifiers and should be used to cite UniProtKB entries. Upon integration into UniProtKB, each entry is assigned a unique accession number, which is called 'Primary (citable) accession number'.<p><a href='/help/accession_numbers' target='_top'>More...</a></p>AccessioniPrimary (citable) accession number: P09339
Secondary accession number(s): Q45059
<p>This subsection of the 'Entry information' section shows the date of integration of the entry into UniProtKB, the date of the last sequence update and the date of the last annotation modification ('Last modified'). The version number for both the entry and the <a href="http://www.uniprot.org/help/canonical%5Fand%5Fisoforms">canonical sequence</a> are also displayed.<p><a href='/help/entry_history' target='_top'>More...</a></p>Entry historyiIntegrated into UniProtKB/Swiss-Prot: July 1, 1989

This is version 148 of the entry and version 4 of the sequence. See complete history.
<p>This subsection of the 'Entry information' section indicates whether the entry has been manually annotated and reviewed by UniProtKB curators or not, in other words, if the entry belongs to the Swiss-Prot section of UniProtKB (<strong>reviewed</strong>) or to the computer-annotated TrEMBL section (<strong>unreviewed</strong>).<p><a href='/help/entry_status' target='_top'>More...</a></p>Entry statusiReviewed (UniProtKB/Swiss-Prot)
