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:
mbtKLysine N-acetyltransferase MbtK; Acyltransferase required for the direct transfer of medium- to long-chain fatty acyl moieties from a carrier protein (MbtL) on to the epsilon-amino group of lysine residue in the mycobactin core. (210 aa)
mbtGLysine-N-oxygenase MbtG (L-lysine 6-monooxygenase) (lysine N6-hydroxylase); Flavoprotein monooxygenase required for N-hydroxylation of the two acylated lysine residues during mycobactin assembly, thus producing the hydroxamate groups necessary for iron sequestration. Is also able, but less efficiently, to hydroxylate L-lysine (non acylated) in vitro. (431 aa)
Rv1885cChorismate mutase; Catalyzes the Claisen rearrangement of chorismate to prephenate. May play some role in the pathogenicity. (199 aa)
mbtBPhenyloxazoline synthase MbtB (phenyloxazoline synthetase); Involved in the initial steps of the mycobactin biosynthetic pathway. Putatively couples activated salicylic acid with serine or threonine and cyclizes this precursor to the hydroxyphenyloxazoline ring system present in this class of siderophores. Essential for growth in macrophages; Belongs to the ATP-dependent AMP-binding enzyme family. MbtB subfamily. (1414 aa)
pptTRv2794c, (MTV002.59c), len: 227 aa. PptT,phosphopantetheinyl transferase, equivalent to Q9Z5I5|ML1547|MLCB596.23 putative iron-chelating complex subunit from Mycobacterium leprae (227 aa), FASTA scores: opt: 1248, E(): 9.1e-77, (79.75% identity in 227 aa overlap). Also highly similar to various proteins e.g. Q9F0Q6|PPTA phosphopantetheinyl transferase from Streptomyces verticillus (246 aa), FASTA scores: opt: 692,E(): 2.8e-39, (46.65% identity in 225 aa overlap); O88029|SC5A7.23 hypothetical 24.5 KDA protein from Streptomyces coelicolor (226 aa), FASTA scores: opt: 679,E(): 2e-38, (46. [...] (227 aa)
ppsAPhenolpthiocerol synthesis type-I polyketide synthase PpsA; Involved in the elongation of either C22-24 fatty acids by the addition of malonyl-CoA and methylmalonyl-CoA extender units to yield phthiocerol derivatives. (1876 aa)
ppsBPhenolpthiocerol synthesis type-I polyketide synthase PpsB; Involved in the elongation of either C22-24 fatty acids by the addition of malonyl-CoA and methylmalonyl-CoA extender units to yield phthiocerol derivatives. (1538 aa)
ppsCPhenolpthiocerol synthesis type-I polyketide synthase PpsC; Involved in the elongation of either C22-24 fatty acids by the addition of malonyl-CoA and methylmalonyl-CoA extender units to yield phthiocerol derivatives. (2188 aa)
ppsDPhenolpthiocerol synthesis type-I polyketide synthase PpsD; Involved in the elongation of either C22-24 fatty acids by the addition of malonyl-CoA and methylmalonyl-CoA extender units to yield phthiocerol derivatives. (1827 aa)
fadD22P-hydroxybenzoyl-AMP ligase FadD22; Catalyzes the adenylation of p-hydroxybenzoic acid (pHBA) to form p-hydroxybenzoic acid-AMP (pHBA-AMP), which is converted directly to p-hydroxybenzoyl-S-FadD22 (pHBA-S-FAdD22) thioester intermediate in a CoA-independent manner by attack of the phosphopantetheine thiol of FadD22. Usually, this intermediate primes the biosynthesis of the phenolphthiocerol (PPOL) by presenting the pHBA starter unit for elongation by Pks15/1, but M.tuberculosis lacks Pks15/1 due to a natural frameshift and thus is unable to produce PPOL. Belongs to the ATP-dependent AMP [...] (705 aa)
entCProbable isochorismate synthase EntC (isochorismate hydroxymutase) (enterochelin biosynthesis); Catalyzes the conversion of chorismate to isochorismate. (372 aa)
mbtIIsochorismate synthase MbtI; Involved in the incorporation of salicylate into the virulence-conferring salicylate-based siderophore mycobactin. Catalyzes the initial conversion of chorismate to yield the intermediate isochorismate (isochorismate synthase activity), and the subsequent elimination of the enolpyruvyl side chain to give salicylate (isochorismate pyruvate-lyase activity). In the absence of magnesium, MbtI displays a chorismate mutase activity and converts chorismate to prephenate. (450 aa)
ideRIron-dependent repressor and activator IdeR; Metal-dependent DNA-binding protein that controls transcription of many genes involved in iron metabolism. Acts as a repressor of siderophore biosynthesis and as a positive modulator of iron storage. Also regulates expression of transporters, proteins involved in siderophore synthesis, iron storage and transcriptional regulators. (230 aa)
Rv0948cProbable mycolyl transferase, pseudogene; Catalyzes the Claisen rearrangement of chorismate to prephenate. Probably involved in the aromatic amino acid biosynthesis. (105 aa)
mbtLAcyl carrier protein (ACP) MbtL; Acyl carrier protein involved in the formation of acyl-S-ACP intermediates within the mycobactin biosynthesis process. The aliphatic chains carried by ACP are subsequently transferred on to the mycobactin core by MbtK. (106 aa)
mbtNAcyl-CoA dehydrogenase MbtN; Catalyzes the dehydrogenation at the alpha-beta position of ACP-bound acyl chains. This results in the introduction of a double bond in the lipidic chain, which is further transferred to the epsilon- amino group of lysine residue in the mycobactin core by MbtK. Belongs to the acyl-CoA dehydrogenase family. (386 aa)
