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
cyaRv1625c, (MT1661, MTCY01B2.17c), len: 443 aa. Cya,membrane-anchored adenylyl cyclase (see citations below). C-terminal half is similar to region in numerous eukaryotic adenylate and guanylate cyclases. N-terminal half hydrophobic. FASTA score: CYG2_RAT|P22717 guanylate cyclase soluble, beta-2 chain (682 aa), FASTA scores: opt: 552,E(): 2.7e-26, (40.3% identity in 226 aa overlap). Some similarity to Rv2435c|MTCY428.11 from Mycobacterium tuberculosis (730 aa), E(): 7e-19. Start changed since first submission (+25 aa). Belongs to adenylyl cyclase class-4/guanylyl cyclase family. (443 aa)    
Predicted Functional Partners:
cpdA
Class III cyclic nucleotide phosphodiesterase (cNMP PDE); Hydrolyzes cAMP to 5'-AMP. Plays an important regulatory role in modulating the intracellular concentration of cAMP, thereby influencing cAMP-dependent processes. Can also hydrolyze cGMP, p- nitrophenyl phosphate (pNPP), bis-(p-nitrophenyl phosphate) (bis(pNPP)), p-nitrophenyl phenylphosphonate (pNPPP) and 2',3'-cAMP. May play a role in pathogenicity, not only by hydrolyzing cAMP, but also by altering properties of the cell wall.

relA
Guanosine-3',5'-bis(diphosphate) 3'-pyrophosphohydrolase; In eubacteria ppGpp (guanosine 3'-diphosphate 5-' diphosphate) is a mediator of the stringent response that coordinates a variety of cellular activities in response to changes in nutritional abundance. This enzyme catalyzes both the formation of pppGpp, which is then hydrolyzed to form ppGpp, as well as the hydrolysis of ppGpp. RelA is probably a key factor in the pathogenesis of M.tuberculosis as it regulates the intracellular concentrations of (p)ppGpp.

pykA
Rv1617, (MTCY01B2.09), len: 472 aa. Probable pykA,pyruvate kinase. FASTA best: Q46078 pyruvate kinase from corynebacterium glutamicum (475 aa), opt: 2221, E(): 0,(72.2% identity in 468 aa overlap). Belongs to the pyruvate kinase family. Phosphorylated in vitro by PknJ|Rv2088 (See Arora et al., 2010).
   
 0.911
ndkA
Probable nucleoside diphosphate kinase NdkA (NDK) (NDP kinase) (nucleoside-2-P kinase); Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate; Belongs to the NDK family.
    
 0.911
Rv1624c
Rv1624c, (MTCY01B2.16c), len: 195 aa. Probable membrane protein, first start taken. Some similarity to Rv3155 nuoK, NADH dehydrogenase chain K from M. tuberculosis. Also similar to AAK72093.1|AF196488 hypothetical protein from Mycobacterium smegmatis (205 aa). Identities = 117/195 (60%).
