The DNA in the Pre-initiation complex is considerably compacted relative to its length when fully extended, probably due to binding of proteins in addition to the viral integrase. These proteins are not fully clarified, due to the difficulty of biochemical analysis of small amounts of material, but candidates include the viral NC and MA proteins, and the cellular HMGA, BAF, and PSIP1/LEDGF/p75 proteins. Purified integrase is capable of carrying out the terminal cleavage and initial strand transfer reactions.
