STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

SCO3792Putative methionyl tRNA synthetase; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation. (538 aa)    
Predicted Functional Partners:
SCO2571
SCC123.09c, leuS, leucyl-tRNA synthetase (EC 6.1.1.4) len: 966 aa. Highly similar to many leucyl-tRNA synthetases including: Bacillus subtilis SW:SYL_BACSU(EMBL:M88581) (804 aa), fasta scores opt: 508 z-score: 575.2 E(): 1.2e-24 48.1% identity in 941 aa overlap and Mycobacterium leprae SW:SYL_MYCLE(EMBL:Y14967) (972 aa), fasta scores opt: 3887 z-score: 4430.5 E():0 60.1% identity in 977 aa overlap. Contains a Prosite hit to PS00178 Amino-acyl-transfer RNA synthetases class-I signature and a Pfam match to entry PF00133 tRNA-synt_1, tRNA synthetases class I (I, L, M and V).

SCO5547
glutamyl-tRNA synthetase; Catalyzes the attachment of glutamate to tRNA(Glu) in a two- step reaction: glutamate is first activated by ATP to form Glu-AMP and then transferred to the acceptor end of tRNA(Glu).
  
 0.952
SCO2076
Putative isoleucyl-tRNA synthetase; Catalyzes the attachment of isoleucine to tRNA(Ile). As IleRS can inadvertently accommodate and process structurally similar amino acids such as valine, to avoid such errors it has two additional distinct tRNA(Ile)-dependent editing activities. One activity is designated as 'pretransfer' editing and involves the hydrolysis of activated Val-AMP. The other activity is designated 'posttransfer' editing and involves deacylation of mischarged Val-tRNA(Ile). Belongs to the class-I aminoacyl-tRNA synthetase family. IleS type 2 subfamily.

SCO3304
SCE68.02, argS, probable arginyl-tRNA synthetase, len: 586 aa; similar to many e.g. SW:SYR_ECOLI (EMBL:X15320), argS, Escherichia coli arginyl-tRNA synthetase (577 aa), fasta scores; opt: 1415 z-score: 1562.9 E(): 0, 43.8% identity in 587 aa overlap. Contains Pfam match to entry PF00750 tRNA-synt_1d, tRNA synthetases class I (R) and PS00178 Aminoacyl-transfer RNA synthetases class-I signature.
  
 0.935
SCO5699
Prolyl tRNA synthetase; Catalyzes the attachment of proline to tRNA(Pro) in a two- step reaction: proline is first activated by ATP to form Pro-AMP and then transferred to the acceptor end of tRNA(Pro). As ProRS can inadvertently accommodate and process non-cognate amino acids such as alanine and cysteine, to avoid such errors it has two additional distinct editing activities against alanine. One activity is designated as 'pretransfer' editing and involves the tRNA(Pro)-independent hydrolysis of activated Ala-AMP. The other activity is designated 'posttransfer' editing and involves dea [...]

SCO1657
Putative methionine synthase; Catalyzes the transfer of a methyl group from methyl- cobalamin to homocysteine, yielding enzyme-bound cob(I)alamin and methionine. Subsequently, remethylates the cofactor using methyltetrahydrofolate.

SCO1294
SCBAC36F5.05c, possible cystathionine gamma-synthase, len: 407 aa; similar to SW:METB_HAEIN (EMBL:U32694) Haemophilus influenzae cystathionine gamma-synthase (EC 4.2.99.9) MetB or HI0086, 369 aa; fasta scores: opt: 625 Z-score: 685.3 bits: 135.6 E(): 1.5e-30; 34.127% identity in 378 aa overlap. Contains Pfam match to entry PF01053 Cys_Met_Meta_PP, Cys/Met metabolism PLP-dependent enzyme and match to Prosite entry PS01050 Uncharacterized protein family UPF0031 signature 2.

Similar to many e.g. SW:MEGL_PSEPU (EMBL:D88554), mdeA, Pseudomonas putida methionine gamma-lyase (398 aa), fasta scores; opt: 608 z-score: 653.6 E(): 4.5e-29, 36.9% identity in 404 aa overlap. Highly similar to TR:Q53668 (EMBL:X91393) Streptomyces antibioticus hypothetical protein found upstream of the abaB gene (232 aa) (87.1% identity in 232 aa overlap). Contains Pfam match to PF0105 [...]

Contains Pfam match to entry PF00551 formyl_transf, Formyl transferase.

SCO1473
methionyl-tRNA formyltransferase; Attaches a formyl group to the free amino group of methionyl- tRNA(fMet). The formyl group appears to play a dual role in the initiator identity of N-formylmethionyl-tRNA by promoting its recognition by IF2 and preventing the misappropriation of this tRNA by the elongation apparatus; Belongs to the Fmt family.
