Crystal structure of human cytosolic aspartyl-tRNA synthetase (DRS) in complex with glutathion-S transferase (GST) domains from Aminoacyl tRNA synthase complex-interacting multifunctional protein 2 (AIMP2) and glutamyl-prolyl-tRNA synthetase (EPRS)
GST conjugates reduced glutathione to a variety of targets including S-crystallin from squid, the eukaryotic elongation factor 1-gamma, the HSP26 family of stress-related proteins and auxin-regulated proteins in plants. Stringent starvation proteins ...
GST conjugates reduced glutathione to a variety of targets including S-crystallin from squid, the eukaryotic elongation factor 1-gamma, the HSP26 family of stress-related proteins and auxin-regulated proteins in plants. Stringent starvation proteins in E. coli are also included in the alignment but are not known to have GST activity. The glutathione molecule binds in a cleft between N and C-terminal domains. The catalytically important residues are proposed to reside in the N-terminal domain [1]. In plants, GSTs are encoded by a large gene family (48 GST genes in Arabidopsis) and can be divided into the phi, tau, theta, zeta, and lambda classes [2].
This is a thioredoxin like domain found in AIMP2 proteins (Aminoacyl tRNA synthetase complex interacting multifunctional protein 2). Aimp2 is a component of human multi-tRNA synthetase complex (MSC). MSC is a macromolecular protein complex consisting ...
This is a thioredoxin like domain found in AIMP2 proteins (Aminoacyl tRNA synthetase complex interacting multifunctional protein 2). Aimp2 is a component of human multi-tRNA synthetase complex (MSC). MSC is a macromolecular protein complex consisting of nine different ARSs and three ARS-interacting multifunctional proteins (AIMPs) [1].
This is the N-terminal domain of nuclear-export cofactor Arc1p (Arc1p-N). Arc1p-N and GluRS-N are known to be necessary and sufficient for formation of the yeast aaRS complex in vivo and in vitro. They are likely to form a stable complex with each ot ...
This is the N-terminal domain of nuclear-export cofactor Arc1p (Arc1p-N). Arc1p-N and GluRS-N are known to be necessary and sufficient for formation of the yeast aaRS complex in vivo and in vitro. They are likely to form a stable complex with each other. Arc1p-N adopts a fold similar to the C-terminal domain of glutathione S-transferase (GST-C).
This family contains OB-fold domains that bind to nucleic acids [4]. The family includes the anti-codon binding domain of lysyl, aspartyl, and asparaginyl -tRNA synthetases (See Pfam:PF00152). Aminoacyl-tRNA synthetases catalyse the addition of an am ...
This family contains OB-fold domains that bind to nucleic acids [4]. The family includes the anti-codon binding domain of lysyl, aspartyl, and asparaginyl -tRNA synthetases (See Pfam:PF00152). Aminoacyl-tRNA synthetases catalyse the addition of an amino acid to the appropriate tRNA molecule EC:6.1.1.-. This family also includes part of RecG helicase involved in DNA repair. Replication factor A is a hetero-trimeric complex, that contains a subunit in this family [2,3]. This domain is also found at the C-terminus of bacterial DNA polymerase III alpha chain.
