Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>-Experimental evidence at protein leveli <p>This indicates the type of evidence that supports the existence of the protein. Note that the 'protein existence' evidence does not give information on the accuracy or correctness of the sequence(s) displayed.<p><a href='/help/protein_existence' target='_top'>More...</a></p>

<p>This section provides any useful information about the protein, mostly biological knowledge.<p><a href='/help/function_section' target='_top'>More...</a></p>Functioni

An essential GTPase that binds both GDP and GTP, with nucleotide exchange occurring on the order of seconds whereas hydrolysis occurs on the order of minutes. Plays a role in numerous processes, including cell cycle regulation, energy metabolism, as a chaperone for 16S rRNA processing and 30S ribosomal subunit biogenesis. One of at least 4 proteins (Era, RbfA, RimM and RsgA/YjeQ) that assist in the late assembly stage of the 30S ribosomal subunit. Its presence in the 30S subunit may prevent translation initiation. Seems to be critical for maintaining cell growth and cell divison rates; a dramatic reduction in Era protein levels temporarily arrests cell growth just before cytokinesis (at the predivisional two-cell stage) and delays cell division. Era mutant era1 suppresses some temperature-sensitive mutations that affect DNA replication and chromosome partitioning and segregation. The dominant-negative Era-de mutant which is missing residues in a putative effector region, is unable to complement the disruption mutant; upon overproduction it shows a significant decrease in cell viability and a synthetic lethal phenotype in the presence of acetate. Era function probably overlaps RbfA (PubMed:16825789). Binds to the pre-30S ribosomal subunit through several stages of protein assembly (PubMed:20188109).4 Publications

Miscellaneous

When overexpressed partially suppresses the slow growth and decreased 70S ribosome phenotype of an rsgA knockout; RsgA may be involved in 30S ribosomal subunit biogenesis (PubMed:18223068). When overexpressed partially suppresses the 30S ribosomal subunit assembly defects and cold-sensitivity of an rbfA knockout; an era mutant missing residues 39-49 fully suppresses these phenotypes (PubMed:12753192). Overexpression is not able to suppress a rimM disruption phenotype nor a C23U mutation in 16S rRNA. Also suppresses temperature-sensitive mutations in DNA primase (PubMed:9093842).3 Publications

    Lethality. In the presence of 1% protein cells grow extremely slowly and are blocked at the predivisional two-cell stage of the cell cycle. In the absence of Era and Rnc there is an additional defect in chromosome partitioning. In depletion experiments cells grow normally for 2 hours when protein levels fall. After 4 hours 16S rRNA levels decrease with a concomitant rise in the 17S precursor rRNA molecule (extra sequences at both the 5' and 3' end compared to mature 16S rRNA) and a loss of 70S ribosome assembly.3 Publications

    <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: P06616
    Secondary accession number(s): Q2MAG4
    <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: January 1, 1988

    This is version 197 of the entry and version 2 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)
