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

[Homology]
Score
metHMethionine synthase; Catalyzes the transfer of a methyl group from methyl- cobalamin to homocysteine, yielding enzyme-bound cob(I)alamin and methionine. Subsequently, remethylates the cofactor using methyltetrahydrofolate (By similarity); Belongs to the vitamin-B12 dependent methionine synthase family. (1192 aa)    
Predicted Functional Partners:
metE
5-methyltetrahydropteroyltriglutamate--homocysteine methyltransferase; Catalyzes the transfer of a methyl group from 5- methyltetrahydrofolate to homocysteine resulting in methionine formation; Belongs to the vitamin-B12 independent methionine synthase family.

Rv2172c
Conserved protein; Rv2172c, (MTV021.05c), len: 301 aa. Conserved protein, equivalent to Mycobacterium leprae conserved hypothetical protein ML0901 (304 aa). FASTA scores: opt: 1656, E(): 7.7e-98; 81.271% identity in 299 aa overlap (1-299:1-299) >emb|CAA18681.1| (AL022602) >gi|13092971|emb|CAC31282.1| (AL583920).

metB
Cystathionine gamma-synthase MetB (CGS) (O-succinylhomoserine [thiol]-lyase); Catalyzes the formation of L-cystathionine from O-succinyl-L- homoserine (OSHS) and L-cysteine, via a gamma-replacement reaction (By similarity). In the absence of thiol, catalyzes gamma-elimination to form 2-oxobutanoate, succinate and ammonia.

metK
S-adenosylmethionine synthase; Catalyzes the formation of S-adenosylmethionine (AdoMet) from methionine and ATP. The overall synthetic reaction is composed of two sequential steps, AdoMet formation and the subsequent tripolyphosphate hydrolysis which occurs prior to release of AdoMet from the enzyme.
