Glycine 47-50 peptidylprolyl isomerase A Homo sapiens 108-112 9385632-2 1997 We demonstrate that the capsid sequence 87His-Ala-Gly-Pro-Ile-Ala92 (87HAGPIA92) encompasses the primary cyclophilin A binding site and present an X-ray crystal structure of the CypA/HAGPIA complex. Glycine 50-53 peptidylprolyl isomerase A Homo sapiens 105-118 15147195-1 2004 The prolyl isomerase cyclophilin A (CypA) is required for efficient HIV-1 replication and is incorporated into virions through a binding interaction at the Gly-Pro(222) bond located within the capsid domain of the HIV-1 Gag precursor polyprotein (Pr(gag)). Glycine 156-159 peptidylprolyl isomerase A Homo sapiens 36-40 15147195-3 2004 To address the proposal that CypA interacts with Gly-Pro sequences in the C-terminal domain of a mature capsid, the interaction between CypA and the natively folded, full-length capsid protein (CA(FL)) has been investigated here using nuclear magnetic resonance spectroscopy. Glycine 49-52 peptidylprolyl isomerase A Homo sapiens 29-33 11929983-4 2002 We show here, using NMR exchange spectroscopy, that CypA does not only bind to CA(N) but also catalyzes efficiently the cis/trans isomerization of the Gly-89-Pro-90 peptide bond. Glycine 151-154 peptidylprolyl isomerase A Homo sapiens 52-56 10026140-2 1999 CyPA binds to the previously identified Gly-Pro90 site of the capsid protein p24, but its role remained unclear. Glycine 40-43 peptidylprolyl isomerase A Homo sapiens 0-4 10026140-5 1999 Peptides corresponding to these regions showed higher affinities (Kd approximately 0.3 microM) for both CyPA and cyclophilin B than the best peptide derived from the Gly-Pro90 site ( approximately 8 microM) and thus revealed new sequence motifs flanking Gly-Pro that are important for tight interaction of peptide ligands with cyclophilins. Glycine 166-169 peptidylprolyl isomerase A Homo sapiens 104-108 10026140-5 1999 Peptides corresponding to these regions showed higher affinities (Kd approximately 0.3 microM) for both CyPA and cyclophilin B than the best peptide derived from the Gly-Pro90 site ( approximately 8 microM) and thus revealed new sequence motifs flanking Gly-Pro that are important for tight interaction of peptide ligands with cyclophilins. Glycine 166-169 peptidylprolyl isomerase A Homo sapiens 327-339 10026140-6 1999 Between CyPA and an immature (unprocessed) form of p24, a Kd of approximately 8 microM was measured, which corresponded with the Kd of the best of the Gly-Pro90 peptides, indicating an association via this site. Glycine 151-154 peptidylprolyl isomerase A Homo sapiens 8-12 9385632-5 1997 Comparison with the recently determined structures of CypA in complexes with larger fragments of the HIV-1 capsid protein demonstrates that CypA recognition of these hexapeptides involves contacts with peptide residues Ala(Val) 88, Gly 89, and Pro 90, and is independent of the context of longer sequences. Glycine 232-235 peptidylprolyl isomerase A Homo sapiens 140-144 9385632-2 1997 We demonstrate that the capsid sequence 87His-Ala-Gly-Pro-Ile-Ala92 (87HAGPIA92) encompasses the primary cyclophilin A binding site and present an X-ray crystal structure of the CypA/HAGPIA complex. Glycine 50-53 peptidylprolyl isomerase A Homo sapiens 178-182 24991000-3 2014 Inspection of the CA sequences of lentiviruses reveals that several species of simian immunodeficiency viruses (SIVs) have lost the glycine-proline motif in the helix 4-5 loop important for CypA binding; instead, the helix 4-5 loop in these SIVs exhibits an increase in the number of glutamine residues. Glycine 132-139 peptidylprolyl isomerase A Homo sapiens 190-194 9032343-2 1997 Elucidation of the biochemical role of CyPA would be aided by a detailed analysis of the genetic requirements for the formation of the Gag-CyPA complex; previous experiments have demonstrated the requirement for a critical proline and the immediately preceding glycine, located within the capsid domain of Gag, but nothing is known about the necessary CyPA residues.
