Binds to ssDNA and to an array of partner proteins to recruit them to their sites of action during DNA metabolism.[HAMAP-Rule:MF_00984] Publication Abstract from PubMed Single-stranded DNA-binding protein (SSB) is essential for all DNA-dependent cellular processes. SSB inhibitors have been recently suggested as broad-spectrum antibacterial agents in antibiotic development. In this paper, we report the first inhibitor-complexed crystal structure of SSB from Pseudomonas aeruginosa PAO1 (PaSSB) at 2.68A resolution (PDB entry 5YUN). The inhibitor, myricetin, is a flavonol that possesses many pharmacological activities, such as anticancer, anti-inflammatory, and antibacterial properties, and is beneficial for humans. Four monomers of PaSSB and two of myricetins were found per asymmetric unit. Various interactions between myricetin and PaSSB were examined. Among these, four residues in PaSSB, Lys7, Arg62, Glu80, and Gly107 were found crucial for forming hydrogen bond to myricetin. These two myricetins occupy the grooves for ssDNA-binding of SSB that may prevent ssDNA-wrapping and ssDNA-binding stably from SSB. In addition to explaining how SSB can be inhibited, the myricetin-SSB interaction modes in this paper may also provide insights into how myricetin can bind and inhibit proteins on cancer-signaling pathways.
