SYSTEMATIC NAME
IUBMB Comments
L-methionine:tRNAMet ligase (AMP-forming)
In those organisms producing N-formylmethionyl-tRNAfMet for translation initiation, this enzyme also recognizes the initiator tRNAfMet and catalyses the formation of L-methionyl-tRNAfMet, the substrate for EC 2.1.2.9, methionyl-tRNA formyltransferase.

GENERAL INFORMATION
ORGANISM
UNIPROT
COMMENTARY hide
LITERATURE
evolution
-
MetRS from nematode is functionally related to human MetRS despite the fact that their appended tRNA-binding domains have distinct structural folds, and are not orthologues
metabolism
-
the single MetRS of Trypanosoma brucei is essential for normal cell growth
physiological function
-
the enzyme also provides a cytosolic anchoring site for aminoacyl-tRNA synthetase-interacting multifunctional protein-3 (AIMP3)/p18, a potent tumor suppressor that is translocated to the nucleus for DNA repair upon DNA damage which is released from the enzyme by UV irradiation-induced stress. The enzyme plays a role as a coregulator with eukaryotic initiation factor-2 subunit-alpha for general control nonrepressed-2-mediated translational inhibition and as a coupler of translational inhibition and DNA repair following DNA damage by releasing bound tumor suppressor AIMP3 for its nuclear translocation
additional information
-
the catalytic domains of class I aminoacyl-tRNA synthetases are built around a conserved Rossmann nucleotide binding fold, with additional polypeptide domains responsible for tRNA binding or hydrolytic editing of misacylated substrates, structural comparisons of class Ia and Ib enzymes, overview. Structural integrity of the helix-turn-strand-helix motif contributes more to tRNA aminoacylation than does amino acid identity

cysteic acid
-
stimulates
cysteine
-
stimulates
elongation factor EF-1alpha
-
activates, assists in dissociation of Met-tRNAMet from the enzyme, the aminoacylated tRNA is transfered from to the enzyme to the elongation factor
-
polymerase I
-
required by the nucleolar located enzyme

required by the nucleolar located enzyme
SO32-
-
stimulates
spermine
slight stimulation, additionally spermine increases the enzyme activity by stabilizing conformation of negatively charged DNA
additional information
bovine serum albumin has no effect on the enzyme
