Hydrogen-bond motifs in the crystals of hydrophobic amino acids
Acta Crystallographica Section B: Structural Science, 2008A computer program has been developed to survey a set of crystal structures for hydrogen-bond motifs. Possible ring and chain motifs are generated automatically from a user-defined list of interacting molecular fragments and intermolecular interactions.

Avoided motifs: short amino acid strings missing from protein datasets [PDF]
Biological Chemistry, 2021 Abstract According to the amino acid composition of natural proteins, it could be expected that all possible sequences of three or four amino acids will occur at least once in large protein datasets purely by chance. However, in some species or cellular context, specific short amino acid motifs are missing due to unknown reasons.

Novel motifs in amino acid permease genes from Leishmania
Biochemical and Biophysical Research Communications, 2004Eight amino acid permease genes from the protozoan parasite Leishmania donovani (AAPLDs) were cloned, sequenced, and shown to be expressed in promastigotes. Seven of these belong to the amino acid transporter-1 and one to the amino acid polyamino-choline superfamilies.

Conservation of amino-acid sequence motifs in lentivirus Vif proteins
Virus Genes, 1992The nonstructural/regulatory genes of human immunodeficiency virus type 1 (HIV-1) and other lentiviruses are believed to play an important role in the replication and pathogenesis of these viruses. In HIV-1 and other lentiviruses, the vif (viral infectivity factor) open reading frame (ORF) (also termed sor or Q in some lentivirus genomes) is located in

Catalysis with Phosphine-Containing Amino Acids in Various “Turn” Motifs
The Journal of Organic Chemistry, 2004We have been actively involved in the development of parallel approaches for the discovery of phosphine ligands. Our approach has been based on the incorporation of phosphine-containing amino acids into peptide sequences that are designed to have stable secondary structures.

Occurrence of six-amino-acid motifs in three eukaryotic proteomes
Molecular Biology, 2012Currently 18 hereditary neurological diseases are known to be associated with such mutations as multiple insertions of a single amino acid into the protein sequence. Therefore, investigation of the functional purpose of simple amino acid motifs becomes an important biological task.

Search for Functionally Significant Motifs and Amino Acid Residues of Actin
Molecular Biology, 2018The scientific interest to the structural and functional properties of actin is determined by its abundance in cells. Being an important component of the cytoskeleton, actin is involved in many protein-protein interactions. Using crystal structures and molecular models, we have mapped the amino acid residues that are involved in these interactions and ...
