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

cmaA2
Cyclopropane mycolic acid synthase 2; Catalyzes the formation of trans cyclopropanated ketomycolate or methoxymycolate through the conversion of a double bond to a cyclopropane ring at the proximal position of an oxygenated mycolic acid via the transfer of a methylene group from S-adenosyl-L- methionine. In the absence of MmaA2, CmaA2 has a non-specific cis- cyclopropanating activity and is able to catalyze the conversion of a double bond to a cis cyclopropane ring at the distal position of an alpha mycolic acid. Cyclopropanated mycolic acids are key factors participating in cell envel [...]
