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
Your Input:
tsaAtRNA-Thr(GGU) m(6)t(6)A37 methyltransferase, SAM-dependent; S-adenosyl-L-methionine-dependent methyltransferase responsible for the addition of the methyl group in the formation of N6-methyl-N6-threonylcarbamoyladenosine at position 37 (m(6)t(6)A37) of the tRNA anticodon loop of tRNA(Thr)(GGU) that read codons starting with adenosine. The methyl group of m(6)t(6)A37 appears to slightly improve the efficiency of the tRNA decoding ability. Binds to tRNA. (235 aa)
yjtDPutative methyltransferase; Protein involved in RNA modification; Belongs to the class IV-like SAM-binding methyltransferase superfamily. RNA methyltransferase TrmH family. (228 aa)
trmAtRNA m(5)U54 methyltransferase, SAM-dependent; Dual-specificity methyltransferase that catalyzes the formation of 5-methyluridine at position 54 (m5U54) in all tRNAs, and that of position 341 (m5U341) in tmRNA (transfer-mRNA). (366 aa)
trmHtRNA mG18-2'-O-methyltransferase, SAM-dependent; Catalyzes the 2'-O methylation of guanosine at position 18 in tRNA. Type II methylase, which methylates only a subset of tRNA species; Belongs to the class IV-like SAM-binding methyltransferase superfamily. RNA methyltransferase TrmH family. (229 aa)
trmLtRNA Leu mC34,mU34 2'-O-methyltransferase, SAM-dependent; Methylates the ribose at the nucleotide 34 wobble position in the two leucyl isoacceptors tRNA(Leu)(CmAA) and tRNA(Leu)(cmnm5UmAA). Catalyzes the methyl transfer from S-adenosyl-L-methionine to the 2'-OH of the wobble nucleotide. Recognition of the target requires a pyridine at position 34 and N(6)-(isopentenyl)-2-methylthioadenosine at position 37. (157 aa)
trmItRNA m(7)G46 methyltransferase, SAM-dependent; Catalyzes the formation of N(7)-methylguanine at position 46 (m7G46) in tRNA; Belongs to the class I-like SAM-binding methyltransferase superfamily. TrmB family. (239 aa)
trmDtRNA m(1)G37 methyltransferase, SAM-dependent; Specifically methylates guanosine-37 in various tRNAs. Belongs to the RNA methyltransferase TrmD family. (255 aa)
trmNtRNA1(Val) (adenine(37)-N6)-methyltransferase; Specifically methylates the adenine in position 37 of tRNA(1)(Val) (anticodon cmo5UAC); Belongs to the methyltransferase superfamily. tRNA (adenine-N(6)-)-methyltransferase family. (245 aa)
trmJtRNA mC32,mU32 2'-O-methyltransferase, SAM-dependent; Catalyzes the formation of 2'O-methylated cytidine (Cm32) or 2'O-methylated uridine (Um32) at position 32 in tRNA. Can also methylate adenosine or guanosine, even though these nucleosides are rare or absent at position 32 in the anticodon loop of tRNA. (246 aa)
rlmNDual specificity 23S rRNA m(2)A2503, tRNA m(2)A37 methyltransferase, SAM-dependent; Specifically methylates position 2 of adenine 2503 in 23S rRNA and position 2 of adenine 37 in tRNAs. m2A2503 modification seems to play a crucial role in the proofreading step occurring at the peptidyl transferase center and thus would serve to optimize ribosomal fidelity. Unmodified tRNA is not a suitable substrate for RlmN, which suggests that RlmN works in a late step during tRNA maturation. Belongs to the radical SAM superfamily. RlmN family. (384 aa)
mnmCtRNA 5-methylaminomethyl-2-thiouridine biosynthesis bifunctional protein MnmC; Catalyzes the last two steps in the biosynthesis of 5- methylaminomethyl-2-thiouridine (mnm(5)s(2)U) at the wobble position (U34) in tRNA. Catalyzes the FAD-dependent demodification of cmnm(5)s(2)U34 to nm(5)s(2)U34, followed by the transfer of a methyl group from S-adenosyl-L-methionine to nm(5)s(2)U34, to form mnm(5)s(2)U34; In the N-terminal section; belongs to the methyltransferase superfamily. tRNA (mnm(5)s(2)U34)-methyltransferase family. (668 aa)
cmoBtRNA (cmo5U34)-carboxymethyltransferase, carboxy-SAM-dependent; Catalyzes carboxymethyl transfer from carboxy-S-adenosyl-L- methionine (Cx-SAM) to 5-hydroxyuridine (ho5U) to form 5- carboxymethoxyuridine (cmo5U) at position 34 in tRNAs. Can also catalyze the SAM-dependent methylation of ho5U, with much lower efficiency. (323 aa)
smtAPutative S-adenosyl-L-methionine-dependent methyltransferase; Catalyzes the methylation of 5-carboxymethoxyuridine (cmo5U) to form 5-methoxycarbonylmethoxyuridine (mcmo5U) at position 34 in tRNAs. Four tRNAs (tRNA(Ala1), tRNA(Ser1), tRNA(Pro3) and tRNA(Thr4)) are fully modified with mcmo5U in stationary-phase E.coli. Also present at low frequency in tRNA(Leu3) and tRNA(Val1). (261 aa)
