The annotation and conditions in this rule are derived from the following entries: P27249 (GLND_ECOLI), Q8RQD1 (GLND_AZOBR), P36223 (GLND_AZOVI), P9WN29 (GLND_MYCTU), P41393 (GLND_KLEOX), Q9RAE4 (GLND_RHILV)

If a protein meets these conditions... i

Common conditions

    • Matches HAMAP signature MF_00277
    • taxon = Bacteria
    • fragment ≠ the sequence is fragmented

Special conditions

    • proteome property = NITROGEN_FIXATION=Yes
    • proteome property = NITROGEN_FIXATION=No
    • proteome property ≠ NITROGEN_FIXATION=*
    • Subsequence at position 350 - 708 aligns to entry P27249 (individually applies "Uridylyl-removing")
    • Subsequence at position @NTER@ - 349 aligns to entry P27249 (individually applies "Uridylyltransferase")

... then these annotations are applied i

<p>This subsection of the ‘Function’ section describes regulatory mechanisms for enzymes, transporters or microbial transcription factors, and reports the components which regulate (by activation or inhibition) the reaction.<p><a href='/help/activity_regulation' target='_top'>More...</a></p>Activity regulationi

  • Uridylyltransferase (UTase) activity is inhibited by glutamine, while glutamine activates uridylyl-removing (UR) activity.

  • Modifies, by uridylylation and deuridylylation, the PII regulatory proteins (GlnB and homologs), in response to the nitrogen status of the cell that GlnD senses through the glutamine level. Under low glutamine levels, catalyzes the conversion of the PII proteins and UTP to PII-UMP and PPi, while under higher glutamine levels, GlnD hydrolyzes PII-UMP to PII and UMP (deuridylylation). Thus, controls uridylylation state and activity of the PII proteins, and plays an important role in the regulation of nitrogen fixation and metabolism.

<p>This subsection of the <a href="http://www.uniprot.org/help/function_section">Function</a> section describes the catalytic activity of an enzyme, i.e. a chemical reaction that the enzyme catalyzes.<p><a href='/help/catalytic_activity' target='_top'>More...</a></p>Catalytic activityi

<p>This subsection of the ‘Family and domains’ section provides general information on the biological role of a domain. The term ‘domain’ is intended here in its wide acceptation, it may be a structural domain, a transmembrane region or a functional domain. Several domains are described in this subsection.<p><a href='/help/domain_cc' target='_top'>More...</a></p>Domaini

  • Has four distinct domains: an N-terminal nucleotidyltransferase (NT) domain responsible for UTase activity, a central HD domain that encodes UR activity, and two C-terminal ACT domains that seem to have a role in glutamine sensing.

<p>This subsection of the ‘Function’ section provides information relevant to cofactors. A cofactor is any non-protein substance required for a protein to be catalytically active. Some cofactors are inorganic, such as the metal atoms zinc, iron, and copper in various oxidation states. Others, such as most vitamins, are organic.<p><a href='/help/cofactor' target='_top'>More...</a></p>Cofactori
