-
ATP + ubiquitin + protein lysine = AMP + diphosphate + protein N-ubiquityllysine
show the reaction diagram
a covalent possibly thiol ester intermediate, is formed between the activating enzyme and ubiquitin; the COOH-terminal Gly of ubiquitin is activated by the enzyme
-
ATP + ubiquitin + protein lysine = AMP + diphosphate + protein N-ubiquityllysine
show the reaction diagram
reaction sequence: 1. initial formation of tightly enzyme-bound ubiquitin adenylate with diphosphate formation from ATP, 2. conversion of this intermediate to form AMP and a covalent enzyme-ubiquitin thiolester, 3. activation of a second molecule of ubiquitin to give a ternary complex of one equivalent each of ubiquitin thiolester and tightly bound ubiquitin adenylate per subunit of enzyme; substrate binding and product release are both strictly ordered, with ATP the leading substrate with respect to ubiquitin and diphosphate the leading product with respect to AMP
-
ATP + ubiquitin + protein lysine = AMP + diphosphate + protein N-ubiquityllysine
show the reaction diagram
both an enzyme-bound COOH-terminal ubiquitin thiolester and a COOH-terminal ubiquitin adenylate are formed
-
ATP + ubiquitin + protein lysine = AMP + diphosphate + protein N-ubiquityllysine
show the reaction diagram
the ubiquitin-activating enzyme E1 catalyzes the formation of ubiquitin adenylate and the transfer of activated ubiquitin to a thiol site on the same enzyme. Following activation, ubiquitin is transferred from the thiol site of E1 to the thiol site of one of several ubiquitin carrier proteins, known as E2s

SYSTEMATIC NAME
IUBMB Comments
Ubiquitin:protein-lysine N-ligase (AMP-forming)
Ubiquitin is coupled to protein by a peptide bond between the C-terminal glycine of ubiquitin and epsilon-amino groups of lysine residues in the protein. An intermediate in the reaction contains one ubiquitin residue bound as a thioester to the enzyme, and a residue of ubiquitin adenylate non-covalently bound to the enzyme.

malfunction
-
elevated expression of E3 ubiquitin ligases MuRF1 and MAFbx is involved in skeletal muscle protein breakdown in rats with thermal injury

Huwe1 balances proliferation and neurogenesis in the developing brain which is subverted in malignant brain tumors
malfunction
-
mahogunin ring finger-1, MGRN1, is a RING domain-containing ubiquitin ligase mutated in mahoganoid, a mouse mutation causing coat color darkening, congenital heart defects, high embryonic lethality, and spongiform neurodegeneration. MGRN1 isoforms decrease MC1R and MC4R signaling to cAMP, without effect on beta2-adrenergic receptor and independently on receptor plasma membrane expression, ubiquitylation, internalization, or stability and occurred upstream of Galphas binding to/activation of adenylyl cyclase. Overexpression of Galpha5 abolishes the inhibitory effect of MGRN1
malfunction
-
MURF3 knockdown in cardiomyocytes by an isogene-specific siRNA leads to upregulation of MURF2 expression. Knockdown of both MURF2 and MURF3 severely disrupts the formation of ordered Z- and M-bands, likely by perturbed tubulin dynamics. It is suggested that ubiquitin-mediated protein turnover and MURF2 in particular play an unrecognised role in the earliest steps of heart muscle differentiation, and that partial complementation of MURF2 deficiency is afforded by MURF3; siRNA knockdown of MURF2 in neonatal rat cardiomyocytes disrupts posttranslational microtubule modification and myofibril assembly, and is only partly compensated by upregulation of MURF3 but not MURF1. It is suggested that ubiquitin-mediated protein turnover and MURF2 in particular play an unrecognised role in the earliest steps of heart muscle differentiation, and that partial complementation of MURF2 deficiency is afforded by MURF3
malfunction
-
downregulation of IBRDC2 induces increased cellular levels and accumulation of the active form of Bax
malfunction
-
the knockdown of Fbxo45 in primary cultured hippocampal neurons results in a greater frequency of miniature excitatory postsynaptic currents
malfunction
-
mice with a MYCBP2-deficiency in peripheral sensory neurons show prolonged thermal hyperalgesia. Loss of MYCBP2 constitutively activates p38 MAPK and increases expression of several proteins involved in receptor trafficking. Loss of MYCBP2 inhibits internalization of transient receptor potential vanilloid receptor 1 and prevents desensitization of capsaicin-induced calcium increases
malfunction
-
selective genetic inactivation of Cbl-b E3 ligase activity (C373AKI/KI knock-in) phenocopies the T cell responses observed when total Cbl-b is ablated, resulting in T cell hyperactivation, spontaneous autoimmunity, and impaired induction of T cell anergy in vivo. Mice carrying a Cbl-b E3 ligase-defective mutation spontaneously reject tumor cells that express human papilloma virus Ags

conjugation of multiple ubiquitins serves as a committed step in the degradation of a variety of intracellular eukaryotic proteins by the 26S proteasome. Conjugates are formed via a three-enzyme cascade. The initial step requires ubiquitin-activating enzyme, E1, which couples ubiquitin activation to ATP hydrolysis

mouse Ube2g2 (conjugating enzyme E2) and human gp78 (ligase E3), an endoplasmic reticulum (ER)-associated conjugating system essential for the degradation of misfolded ER proteins, are recombinantly expressed in Escherichia coli. Ube2g2/gp78-mediated polyubiquitination involves preassembly of Lys 48-linked ubiquitin chains at the catalytic cysteine of Ube2g2. The growth of Ube2g2-anchored ubiquitin chains seems to be mediated by an aminolysis-based transfer reaction between two Ube2g2 molecules that each carries a ubiquitin moiety in its active site. Intriguingly, polyubiquitination of a substrate can be achieved by transferring preassembled ubiquitin chains from Ube2g2 to a lysine residue in a substrate

MURF1 shows strong postnatal up-regulation; MURF2 is expressed at the very onset of mouse cardiac differentiation at embryonic day 8.5, and represents a sensitive marker for differentiating myocardium. During cardiac development, expression shifts from the 50 kDa to the 60 kDa A-isoform which dominates postnatally; MURF3 protein expression is negligible during embryonic cardiac development and only upregulated postnatally
