The superimposition of the matrix proteins of FIV (red) with (A) HIV (PDB ID: 1HIW, blue), (B) SIV (PDB ID: 1ECW, green) and (C) EIAV (PDB ID: 1HEK, yellow) matrix proteins.
The structure of full-length p15 was determined by the molecular replacement method using the program MrBUMP [ 59 ] of the CCP4 program suite and the structure of SIV matrix protein (PDB ID: 1ECW) as the search model.
The phase problem was solved by molecular replacement using SIV p17 (PDB ID: 1ECW) as the search model [ 32 ].
The best structural homologues are the EIAV p15 protein (PDB ID: 1HEK), the HIV p17 protein (PDB ID: 1HIW) and the SIV p17 protein (PDB ID: 1ECW) with 21%, 18% and 11% of sequence identity with the FIV p15 protein.
Helices (squiggles along the sequence) of the crystal structures are shown for FIV p15 (this paper), EIAV p15 (PDB ID: 1HEK), HIV p17 (PDB ID: 1HIW) and SIV p17 (PDB ID: 1ECW).

FIV myrMA Q5A/G6S also bears close similarity to SIV MA (PDB: 1ECW) and EIAV MA (PDB: 1HEK), although EIAV is not N-terminally myristylated.
