2ifu has 4 chains (A, B, C and D) integrated together to form the whole molecular structure as shown below:
(chain A= green, chain B= cyan, chain c= purple, and chain d= yellow)
Two molecular components were observed:
sulfate ion (SO4) and selenomethionine (MSE)
Ten sulfate ions were observed. Each ion differs in arrangement as well as orientation related with each chains.
