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

cbiMCobalt ABC transporter, substrate-binding protein; Probably part of the energy-coupling factor (ECF) transporter complex LarMNQO involved in nickel import. Belongs to the CbiM family. NikM subfamily. (328 aa)    
Predicted Functional Partners:
larO
Cobalt ABC transporter, ATP-binding protein; Probable ATP-binding component of the energy-coupling factor (ECF) transporter complex LarMNQO involved in nickel import. LarO is presumably responsible for energy coupling to the transport system.
 
 0.999
larQ
Cobalt ABC transporter, permease protein; Probable transmembrane component of the energy-coupling factor (ECF) transporter complex LarMNQO involved in nickel import.

larR
Transcription regulator, Crp/FNR family; Positive transcriptional regulator that is absolutely required for the expression of lactate racemase (Lar) activity. Controls Lar expression by sensing the L-/D-lactate ration. Binds to a 16-bp palindromic sequence (Lar box motif) that is present in the larR- larA intergenic region, allowing transcription of the larABCDE operon.

larB
Lactate racemization operon protein LarB; Involved in the biosynthesis of a nickel-pincer cofactor ((SCS)Ni(II) pincer complex). Carboxylates the pyridinium ring of nicotinic acid adenine dinucleotide (NaAD) and cleaves the phosphoanhydride bond to release AMP and generate pyridinium-3,5- biscarboxylic acid mononucleotide (P2CMN). LarB can hydrolyze NaAD directly or it first forms an adduct with NaAD that releases AMP and reacts with bicarbonate/CO2 to generate P2CMN. Is required for the activation of the lactate racemase LarA. May also be involved in the activation of other nickel-pin [...]

larE
Lactate racemization operon protein LarE; Involved in the biosynthesis of a nickel-pincer cofactor ((SCS)Ni(II) pincer complex). Catalyzes the ATP-dependent incorporation of two sulfur atoms in pyridinium-3,5-biscarboxylic acid mononucleotide (P2CMN) to yield pyridinium-3,5-bisthiocarboxylic acid mononucleotide (P2TMN). The source of sulfur is the enzyme itself: Cys-176 of LarE is the sulfur donor, thereby being converted into dehydroalanine, and is not regenerated in vivo. Thus, two molecules of LarE undergo sacrificial sulfur transfer to create one P2TMN. Binds nickel. Is required fo [...]

larC1
Lactate racemization operon protein LarC,N-terminal domain; Involved in the biosynthesis of a nickel-pincer cofactor ((SCS)Ni(II) pincer complex). Binds Ni(2+), and functions in nickel delivery to pyridinium-3,5-bisthiocarboxylic acid mononucleotide (P2TMN), to form the mature cofactor. Is required for the activation of the lactate racemase LarA. May also be involved in the activation of other nickel-pincer cofactor-dependent enzymes.
 
    0.886
larA
Lactate racemization operon protein LarA; Catalyzes the interconversion between the D- and L-isomers of lactate. May act as a rescue enzyme to ensure D-lactate production in physiological conditions where its production by the D-lactate dehydrogenase LdhD is not sufficient. D-Lactate is absolutely required for growth of L.plantarum and is an essential component of the cell wall peptidoglycan in this species, where it is incorporated as the last residue of the muramoyl-pentadepsipeptide peptidoglycan precursor; its incorporation confers high level of vancomycin resistance.
