| A '''ubiquitin ligase''' (also called an E3 ubiquitin ligase) is a [[ligase]] [[enzyme]] that combines with a ubiquitin-containing E2 [[ubiquitin-conjugating enzyme]], recognizes the target protein that is to be ubiquinated, and causes the attachment of [[ubiquitin]] to a [[lysine]] on the target protein via an [[isopeptide bond]]. An E3 ubiquitin ligase targets specific protein substrates for degradation by the [[proteasome]]. In general, the ubiquitin ligase is involved in poly-ubiquitination: a second ubiquitin is attached to the first, a third is attached to the second, and so forth. Poly-ubiquitination marks proteins for degradation by the proteasome.
| |
| | |
| However, there are some ubiquitination events that are limited to mono-ubiquitination, in which only a single ubiquitin is added by the ubiquitin ligase to a substrate molecule. Mono-ubiquitinated proteins are not targeted to the proteasome for degradation, but may instead be altered in their cellular location or function, for example, via binding other proteins that have domains capable of binding ubiquitin.{{Citation needed|date=September 2011}}
| |
| | |
| Further complicating matters, different lysines on ubiquitin can be targeted by an E3 to make chains. The most common lysine is Lys48 on the ubiquitin chain. This is the lysine used to make polyubiquitin, which is recognized by the proteasome. However, Lys63 can also be used, and chains using this lysine are important for [[DNA]] repair, among other functions.
| |
| | |
| ==Overview==
| |
| In [[enzymology]], an '''ubiquitin-protein ligase''' ({{EC number|6.3.2.19}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]
| |
| | |
| :ATP + ubiquitin + protein lysine <math>\rightleftharpoons</math> AMP + diphosphate + protein N-ubiquityllysine
| |
| | |
| The 3 [[substrate (biochemistry)|substrates]] of this enzyme are [[adenosine triphosphate|ATP]], [[ubiquitin]], and [[protein lysine]], whereas its 3 [[product (chemistry)|products]] are [[adenosine monophosphate|AMP]], [[diphosphate]], and [[protein N-ubiquityllysine]].
| |
| | |
| This enzyme belongs to the family of [[ligase]]s, to be specific those forming carbon-nitrogen bonds as acid-D-amino-acid ligases (peptide synthases). The systematic name of this enzyme class is '''ubiquitin:protein-lysine N-ligase (AMP-forming)'''. This enzyme is also called '''ubiquitin-activating enzyme'''. This enzyme participates in 3 [[metabolism|metabolic pathways]]: [[ubiquitin-mediated proteolysis]], [[parkinson's disease]], and [[huntington's disease]].
| |
| | |
| ==Structural studies==
| |
| | |
| As of late 2007, 75 [[tertiary structure|structures]] have been solved for this class of enzymes, with [[Protein Data Bank|PDB]] accession codes {{PDB link|1A3S}}, {{PDB link|1AYZ}}, {{PDB link|1C4Z}}, {{PDB link|1FBV}}, {{PDB link|1FXT}}, {{PDB link|1FZY}}, {{PDB link|1I7K}}, {{PDB link|1IYF}}, {{PDB link|1J7D}}, {{PDB link|1JAS}}, {{PDB link|1JAT}}, {{PDB link|1JBB}}, {{PDB link|1KPS}}, {{PDB link|1PZV}}, {{PDB link|1Q34}}, {{PDB link|1QCQ}}, {{PDB link|1TTE}}, {{PDB link|1U9A}}, {{PDB link|1U9B}}, {{PDB link|1UMH}}, {{PDB link|1UMI}}, {{PDB link|1UR6}}, {{PDB link|1W4U}}, {{PDB link|1WD2}}, {{PDB link|1WZV}}, {{PDB link|1WZW}}, {{PDB link|1X23}}, {{PDB link|1XR9}}, {{PDB link|1Y6L}}, {{PDB link|1Y8X}}, {{PDB link|1YH6}}, {{PDB link|1YLA}}, {{PDB link|1YRV}}, {{PDB link|1Z2U}}, {{PDB link|1Z3D}}, {{PDB link|1Z5S}}, {{PDB link|1Z6U}}, {{PDB link|1ZDN}}, {{PDB link|1ZUO}}, {{PDB link|2A4D}}, {{PDB link|2A7L}}, {{PDB link|2AAK}}, {{PDB link|2AWF}}, {{PDB link|2AYV}}, {{PDB link|2BEP}}, {{PDB link|2BF8}}, {{PDB link|2C4O}}, {{PDB link|2C4P}}, {{PDB link|2CLW}}, {{PDB link|2CYX}}, {{PDB link|2E2C}}, {{PDB link|2EKE}}, {{PDB link|2ESK}}, {{PDB link|2ESO}}, {{PDB link|2ESP}}, {{PDB link|2ESQ}}, {{PDB link|2F4W}}, {{PDB link|2FO3}}, {{PDB link|2FUH}}, {{PDB link|2GJD}}, {{PDB link|2GMI}}, {{PDB link|2GRN}}, {{PDB link|2GRO}}, {{PDB link|2GRP}}, {{PDB link|2GRQ}}, {{PDB link|2GRR}}, {{PDB link|2H2Y}}, {{PDB link|2O25}}, {{PDB link|2OB4}}, {{PDB link|2OGB}}, {{PDB link|2ONU}}, {{PDB link|2UCZ}}, {{PDB link|2UYZ}}, {{PDB link|2Z6O}}, and {{PDB link|2Z6P}}.

| ==Ubiquitination system==
| |
| [[File:Ubiquitylation.png|thumb|250 px|Schematic diagram of the ubiquitylation system.]]
| |
| The ubiquitin ligase is referred to as an E3, and operates in conjunction with an [[ubiquitin-activating enzyme|E1 ubiquitin-activating enzyme]] and an [[ubiquitin-conjugating enzyme|E2 ubiquitin-conjugating enzyme]]. There is one major E1 enzyme, shared by all ubiquitin ligases, that uses [[adenosine triphosphate|ATP]] to activate [[ubiquitin]] for [[Conjugation (biochemistry)|conjugation]] and transfers it to an E2 enzyme. The E2 enzyme interacts with a specific E3 partner and transfers the [[ubiquitin]] to the target [[protein]]. The E3, which may be a [[protein complex|multi-protein complex]], is, in general, responsible for targeting ubiquitination to specific [[Substrate (biochemistry)|substrate]] proteins. In some cases, it receives the ubiquitin from the E2 enzyme and transfers it to the target protein; in other cases, it acts by interacting with both the E2 enzyme and the substrate, but never itself receives the ubiquitin.
| |
| | |
| ==Ubiquitin ligase families==
| |
| | |
| The [[anaphase-promoting complex]] (APC) and the [[SCF complex]] ([[Skp1]]-[[Cullin]]-F-box protein complex) are two examples of ubiquitin ligase protein scaffold involved in recognition and ubiquitination of specific target proteins for degradation by the proteasome.
| |
| | |
| Each contains particular protein domains capable of binding the E2 conjugase, as well as a substrate-specific domain for binding the target. Many E2- and substrate-binding domains exist. This wide variety has been discovered to fall into specific groups called ubiquitin-ligase families.

| | |
