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.

MJ_1388Adenosylhomocysteinase (ahcY); Catalyzes the hydrolysis of S-inosyl-L-homocysteine (SIH) to L-homocysteine (Hcy) and inosine. Likely functions in a S-adenosyl-L- methionine (SAM) recycling pathway from S-adenosyl-L-homocysteine (SAH) produced from SAM-dependent methylation reactions. Can also catalyze the reverse reaction in vitro, i.e. the synthesis of SIH from Hcy and inosine. Is specific for SIH and inosine as it is unable to either hydrolyze SAH or synthesize SAH from adenosine and Hcy. Belongs to the adenosylhomocysteinase family. (415 aa)    
Predicted Functional Partners:
metE
5-methyltetrahydropteroyltriglutamate- homocysteine methyltransferase (metE); Catalyzes the transfer of a methyl group to L-homocysteine resulting in methionine formation. Can use methylcobalamin and methylcobinamide as methyl donors, but methylcobalamin is not considered to be the physiological substrate (By similarity).

dadD
N-ethylammeline chlorohydrolase (trzA); Catalyzes the deamination of three SAM-derived enzymatic products, namely 5'-deoxyadenosine, S-adenosyl-L-homocysteine, and 5'- methylthioadenosine, to produce the inosine analogs. Can also deaminate adenosine. The preferred substrate for this enzyme is 5'- deoxyadenosine, but all these substrates are efficiently deaminated. Likely functions in a S-adenosyl-L-methionine (SAM) recycling pathway from S-adenosyl-L-homocysteine (SAH) produced from SAM-dependent methylation reactions. May also be involved in the recycling of 5'-deoxyadenosine, whereup [...]

Ferredoxin II; Similar to SP:P00211 percent identity: 40.00; identified by sequence similarity; putative.

MJ_0100
Conserved hypothetical protein; Similar to PID:1652054 percent identity: 48.63; identified by sequence similarity; putative.

glyA
Serine hydroxymethyltransferase (glyA); Catalyzes the reversible interconversion of serine and glycine with tetrahydromethanopterin (H4MPT) serving as the one-carbon carrier. The use of tetrahydrofolate (THF or H4PteGlu) as the pteridine substrate is 450-fold less efficient than that of H4MPT. Also exhibits a pteridine-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism. Thus, is able to catalyze the cleavage of L-allo-threonine and L-threo- beta-phenylserine; Belongs to the SHMT family.

Conserved hypothetical protein; Similar to GB:D15061 SP:P28634 PID:303558 GB:U00096 PID:1552771 percent identity: 40.68; identified by sequence similarity; putative.

MJ_0209
Conserved hypothetical protein; Catalyzes the condensation of (R)-4-phosphopantoate and beta- alanine to 4'-phosphopantothenate in the CoA biosynthesis pathway. Belongs to the archaeal phosphopantothenate synthetase family.

Conserved hypothetical protein; Similar to GB:X73148 PID:407884 percent identity: 30.97; identified by sequence similarity; putative.

MJ_0406
Ribokinase (rbsK); Catalyzes the phosphorylation of a wide range of nucleosides to yield nucleoside monophosphates. Shows the highest activity for inosine, guanosine and cytidine, but very poor kinase activity with adenosine, thymidine, uridine and xanthosine. ATP is the best phosphate donor, but can also use ITP and GTP. Shows extremely low activity with fructose-6-phosphate; Belongs to the carbohydrate kinase PfkB family.
