Self-Organizing Map for Characterizing Heterogeneous Nucleotide and Amino Acid Sequence Motifs [PDF]
A self-organizing map (SOM) is an artificial neural network algorithm that can learn from the training data consisting of objects expressed as vectors and perform non-hierarchical clustering to represent input vectors into discretized clusters, with ...

Reinvestigating the Photoprotection Properties of a Mycosporine Amino Acid Motif [PDF]
With the growing concern regarding commercially available ultraviolet (UV) filters damaging the environment, there is an urgent need to discover new UV filters. A family of molecules called mycosporines and mycosporine-like amino acids (referred to as MAAs collectively) are synthesized by cyanobacteria, fungi and algae and act as the natural UV filters

Unravelling the Photoprotection Properties of Mycosporine Amino Acid Motifs [PDF]
Photoprotection from harmful ultraviolet (UV) radiation exposure is a key problem in modern society. Mycosporine-like amino acids found in fungi, cyanobacteria, macroalgae, phytoplankton, and animals are already presenting a promising form of natural photoprotection in sunscreen formulations.

Fluorine containing amino acids: synthesis and peptide coupling of amino acids containing the all-cis tetrafluorocyclohexyl motif [PDF]
A synthesis of amino acids carrying the all-cis tetrafluorocyclohexyl ring moiety is demonstrated and protection/deprotection elaborations are illustrated which show that this facially polarised ring motif may be incorporated into peptides.

Motivated Proteins: A web application for studying small three-dimensional protein motifs
Background Small loop-shaped motifs are common constituents of the three-dimensional structure of proteins. Typically they comprise between three and seven amino acid residues, and are defined by a combination of dihedral angles and hydrogen bonding ...
