Structural highlights
3ig9 is a 4 chain structure with sequence from Escherichia phage RB69. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
SOC_BPR69 Capsid decoration protein which helps to stabilize the capsid against extremes of pH and temperature. Once maturation and expansion of the capsid has occured, trimers of soc attach the interfaces between the hexamer of the major capsid protein. Acts as a 'glue' between neighboring hexameric capsomers. Dispensable for the head morphogenesis and phage infection.[HAMAP-Rule:MF_04115]
