Protein

Lipoate-protein ligase A subunit 1

Gene

lplA

Organism
Thermoplasma acidophilum (strain ATCC 25905 / DSM 1728 / JCM 9062 / NBRC 15155 / AMRC-C165)
Status
Reviewed-Annotation score:

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

Part of a lipoate-protein ligase complex that catalyzes both the ATP-dependent activation of exogenously supplied lipoate to lipoyl-AMP and the transfer of the activated lipoyl onto the lipoyl domains of lipoate-dependent enzymes. Can also use octanoate as substrate.3 Publications

Miscellaneous

In contrast to E.coli, where the lipoate-protein ligase is encoded by a single gene product (LplA) with a large N-terminal domain and a small C-terminal domain, the same activity in T.acidophilum is dependent on two separate proteins, corresponding to the two domains of E.coli LplA, respectively.

<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 <a href="http://www.uniprot.org/help/function_section">'Function'</a> section describes the metabolic pathway(s) associated with a protein.<p><a href='/help/pathway' target='_top'>More...</a></p>Pathwayi: protein lipoylation via exogenous pathway

This protein is involved in step 1 and 2 of the subpathway that synthesizes protein N(6)-(lipoyl)lysine from lipoate.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Lipoate-protein ligase A subunit 2 (lplB), Lipoate-protein ligase A subunit 1 (lplA)
  2. Lipoate-protein ligase A subunit 2 (lplB), Lipoate-protein ligase A subunit 1 (lplA)
This subpathway is part of the pathway protein lipoylation via exogenous pathway, which is itself part of Protein modification.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes protein N(6)-(lipoyl)lysine from lipoate, the pathway protein lipoylation via exogenous pathway and in Protein modification.

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
