3bbu is a 1 chain structure with sequence from Escherichia coli. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
HSLR_ECOLI Involved in the recycling of free 50S ribosomal subunits that still carry a nascent chain. Binds RNA more specifically than DNA. Binds with very high affinity to the free 50S ribosomal subunit. Does not bind it when it is part of the 70S ribosome.
