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

thyAThymidylate synthase; Catalyzes the reductive methylation of 2'-deoxyuridine-5'- monophosphate (dUMP) to 2'-deoxythymidine-5'-monophosphate (dTMP) while utilizing 5,10-methylenetetrahydrofolate (mTHF) as the methyl donor and reductant in the reaction, yielding dihydrofolate (DHF) as a by- product. This enzymatic reaction provides an intracellular de novo source of dTMP, an essential precursor for DNA biosynthesis. (320 aa)    
Predicted Functional Partners:
BAP85672.1
Dihydrofolate reductase; Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis.

tdk
Thymidine kinase; ATP binding site [chemical binding]; P-loop containing Nucleoside Triphosphate Hydrolases; cl09099; Walker A motif; Walker B motif; gene_1540; identified by MetaGeneAnnotator; putative; strain coidentity: ATCC 53103 = GG; synonym: Lactobacillus rhamnosus ATCC 53103; thymidine kinase [Lactobacillus rhamnosus GG]; thymidine kinase; Provisional.

BAP85014.1
dUTP diphosphatase; This enzyme is involved in nucleotide metabolism: it produces dUMP, the immediate precursor of thymidine nucleotides and it decreases the intracellular concentration of dUTP so that uracil cannot be incorporated into DNA.
  
 0.960
glyA
Serine hydroxymethyltransferase; Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism.

BAP85868.1
Competence protein ComEB; COG: COG2131; Deoxycytidylate deaminase domain. Deoxycytidylate deaminase catalyzes the deamination of dCMP to dUMP, providing the nucleotide substrate for thymidylate synthase. The enzyme binds Zn++, which is required for catalytic activity. The activity of the..; cd01286; Zn binding site [ion binding]; catalytic motif [active]; competence protein ComEB [Lactobacillus vaginalis ATCC 49540]; gene_1288; identified by MetaGeneAnnotator; putative.

folD
Methenyltetrahydrofolate cyclohydrolase; Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10- methenyltetrahydrofolate to 10-formyltetrahydrofolate.

BAP86692.1
5,10-methylenetetrahydrofolate reductase [Lactobacillus buchneri NRRL B- 30929]; FAD binding site [chemical binding]; Methylenetetrahydrofolate reductase (MTHFR). 5,10-Methylenetetrahydrofolate is reduced to 5-methyltetrahydrofolate by methylenetetrahydrofolate reductase, a cytoplasmic, NAD(P)-dependent enzyme. 5-methyltetrahydrofolate is utilized by methionine synthase..; cd00537; Methylenetetrahydrofolate reductase; pfam02219; TIGRFAM: 5,10-methylenetetrahydrofolate reductase; KEGG: lhe:lhv_1915 5,10-methylenetetrahydrofolate reductase; PFAM: Methylenetetrahydrofolate reductase; gene [...]

Hypothetical protein; ATP-binding site [chemical binding]; COG: COG0125; Pfam: PF02223; InterPro: IPR000062; TMP-binding site; Thymidine monophosphate kinase (TMPK), also known as thymidylate kinase, catalyzes the phosphorylation of thymidine monophosphate (TMP) to thymidine diphosphate (TDP) utilizing ATP as its preferred phophoryl donor. TMPK represents the rate-limiting step..; cd01672; gene_248; identified by MetaGeneAnnotator; putative; pseudogene of thymidylate kinase; thymidylate kinase [Lactobacillus brevis subsp. gravesensis ATCC 27305]; thymidylate kinase; Validated; PRK00698.

tgt
Queuine tRNA-ribosyltransferase; Catalyzes the base-exchange of a guanine (G) residue with the queuine precursor 7-aminomethyl-7-deazaguanine (PreQ1) at position 34 (anticodon wobble position) in tRNAs with GU(N) anticodons (tRNA-Asp, - Asn, -His and -Tyr). Catalysis occurs through a double-displacement mechanism. The nucleophile active site attacks the C1' of nucleotide 34 to detach the guanine base from the RNA, forming a covalent enzyme-RNA intermediate. The proton acceptor active site deprotonates the incoming PreQ1, allowing a nucleophilic attack on the C1' of the ribose to form t [...]
