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

Rv0887cRv0887c, (MTCY31.15c), len: 152 aa. Conserved hypothetical protein, highly similar to others e.g. NP_436346.1|NC_003037 Hypothetical protein from Sinorhizobium meliloti (149 aa); AL132644|SCI8_26 hypothetical protein from Streptomyces coelicolor (194 aa),FASTA scores: opt: 220, E(): 1.5e-07, (33.6% identity in 131 aa overlap); etc. Also shows weak similarity with transposases and related proteins. (152 aa)    
Predicted Functional Partners:
Rv0654
Probable dioxygenase; Catalyzes the oxidative cleavage of several carotenoids and apocarotenoids in vitro. In contrast to other carotenoid oxygenases, cleaves substrates at two different sites, namely the central C15-C15' and an excentric double bond at the C13-C14 position, leading to retinal (C20), beta-apo-14'-carotenal (C22) and beta-apo-13-carotenone (C18) from beta-carotene (C40), as well as the corresponding hydroxylated products from zeaxanthin and lutein. Converts beta-apo- 10'-carotenal (C27) into beta-apo-13-carotenone (C18) and to minor amounts of beta-apo-15-carotenal (ret [...]

sigI
Possible alternative RNA polymerase sigma factor SigI; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma factors are held in an inactive form by a cognate anti-sigma factor until released, although no anti-sigma factor is known for this protein (By similarity).
