2.7.13.3	ATP	-	690397, 690950, 692882, 694232, 701785, 701950, 702402, 702733, 702906, 704312, 704324, 704331, 704333, 705134, 705769, 705772, 705782, 705788, 705793, 706173, 706435, 706513, 739983, 740049, 740070, 740082, 740525, 740621, 740624, 740870, 741136, 741222, 741226, 741235, 741283	
2.7.13.3	ATP	DesK displays a compact structure at the ATP-binding pocket: the ATP lid loop is short with no secondary structural organization and becomes ordered upon ATP loading. Sequence conservation mapping onto the molecular surface, semi-flexible protein-protein docking simulations, and structure-based point mutagenesis present a specific domain-domain geometry during autophosphorylation catalysis	740689	
2.7.13.3	ATP	residue Ser492 resides on the ATP lid, near to the Mg2+ ion that coordinates the gamma-phosphate of ATP in the P4 active site	740869	
2.7.13.3	ATP	the ATP-binding domain of histidine kinases contains conserved motifs essential for autokinase activity. These include G1 and G2 boxes, which have the characteristic glycine signatures DxGxG and GxGxG, respectively	740492	
2.7.13.3	FAD	Slr1759-Var I protein contains 0.11-0.26 mM cofactor per 1 mM protein	701950	
2.7.13.3	flavin	-	682858	
2.7.13.3	flavin	flavin-containing histidine kinase functions as a photoreceptor, the flavin chromophore, upon illumination, forms a cysteinyl-flavin adduct, which is the signaling state that activates the histidine kinase	682858	
2.7.13.3	flavin	flavin-containing histidine kinase functions as a photoreceptor, the flavin chromophore, upon illumination, forms a cysteinyl-flavin adduct, which is the signaling state that activates the histidine kinase, regulates Brucella abortus virulence	682858	
2.7.13.3	FMN	bound to the LovK histidine kinase	740049	
2.7.13.3	GDP	this kinase is uniquely specific for GTP in the forward and GDP in the reverse reaction. The G1 motif of BA2291 is highly modified from ATP specific histidine kinases, binding structure, modeling, overview	692901
