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

Score
PE27Rv2769c, (MTV002.34c), len: 275 aa. PE27, Member of the Mycobacterium tuberculosis PE family (see citation below), highly similar to many (notably in N-terminal part) e.g. P96361|Rv1040c|MTCY10G2.09 from Mycobacterium tuberculosis (275 aa), FASTA scores: opt: 1111, E(): 5.9e-52, (68.55% identity in 283 aa overlap). (275 aa)    
Predicted Functional Partners:
PPE43
Rv2768c, (MTV002.33c), len: 394 aa. PPE43, Member of the Mycobacterium tuberculosis PPE family, highly similar to many e.g. upstream ORF O33312|Rv2770c|MTV002.35c (402 aa), FASTA scores: opt: 1135, E(): 6.1e-51, (62.15% identity in 391 aa overlap); and P96362|Rv1039c|MTCY10G2.10 from M. tuberculosis (391 aa), FASTA scores: opt: 1721,E(): 6.8e-81, (70.35% identity in 398 aa overlap). Equivalent to AAK47157 from Mycobacterium tuberculosis strain CDC1551 (462 aa) but shorter 68 aa.

Rv3778c
Possible aminotransferase; Is essential for optimal growth; Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family.
      
 0.681
hddA
Rv0115, (MTV031.09), len: 386 aa. Possible hddA,D-alpha-D-heptose-7-phosphate kinase (see citation below),similar to several hypothetical proteins and sugar kinases e.g. AAK27850.1|AF324836_3 D-glycero-D-manno-heptose 7-phosphate kinase from Aneurinibacillus thermoaerophilus (341 aa); AAK80995.1|AE007802_11 Sugar kinase from Clostridium acetobutylicum (364 aa). This region is a possible MT-complex-specific genomic island (See Becq et al., 2007).
      
 0.654
Rv2767c
Possible membrane protein; Rv2767c, (MTV002.32c), len: 117 aa (questionable ORF). Possible membrane protein, showing very weak similarity with Q9L2H7|SCC121.09 putative metal transport ABC transporter from Streptomyces coelicolor (256 aa),FASTA scores: opt: 110, E(): 1, (33.05% identity in 112 aa overlap).
     
 0.533
PE27A
Rv3018A, len: 28 aa. PE27A, Member of Mycobacterium tuberculosis PE family (see Brennan and Delogu, 2002), most similar to Rv0285 (102 aa), FASTA scores: opt: 147, E(): 3.5e-05, (92.85% identity in 28 aa overlap); etc.

ldtA
Probable L,D-transpeptidase LdtA; Generates 3->3 cross-links in peptidoglycan, catalyzing the cleavage of the mDap(3)-D-Ala(4) bond of a tetrapeptide donor stem and the formation of a bond between the carbonyl of mDap(3) of the donor stem and the side chain of mDap(3) of the acceptor stem. Is specific for donor substrates containing a stem tetrapeptide since it cannot use pentapeptide stems. Is thought to play a role in adaptation to the nonreplicative state of M.tuberculosis.

PPE44
Rv2770c, (MTV002.35c), len: 382 aa. PPE44, Member of the Mycobacterium tuberculosis PPE family, highly similar to many e.g. downstream ORF O33310|Rv2768c|MTV002.33c from M. tuberculosis (394 aa), FASTA scores: opt: 1135, E(): 2.2e-53, (62.15% identity in 391 aa overlap); and P96362|Rv1039c|MTCY10G2.10 from Mycobacterium tuberculosis (391 aa), FASTA scores: opt: 1010, E(): 1e-46, (55.95% identity in 395 aa overlap). Equivalent to AAK47159 from Mycobacterium tuberculosis strain CDC1551 (402 aa) but shorter 20 aa. Start changed since first submission (-20 aa).
