PTGL

The software tool 'PTGL' or Protein Topology Graph Library is a database application that allows for the representation and retrieval of protein topologies. It uses a graph-theoretical protein model at secondary structure level and offers four linear notations for their characterization. This on-line search tool provides a query browser for data interrogation by string patterns, keyword queries and sequence similarity. Protein topologies are represented both as schematic diagrams and as three-dimensional images.

The Protein Topology Graph Library, also known as PTGL, is an innovative software tool that is designed to help researchers in the field of protein studies. This database application provides a comprehensive representation of protein topologies and allows for the retrieval of relevant data. One of the key features of PTGL is its use of a graph-theoretical protein model at the secondary structure level. This enables researchers to gain a deeper understanding of the underlying structure of proteins.

Moreover, PTGL offers four linear notations for the characterization of protein topologies. This means that users can easily identify and compare different topologies and gain insights into their unique features. The software tool also provides an online search function, which enables users to query the database using string patterns, keyword queries, and sequence similarity.

One of the most exciting features of PTGL is its ability to represent protein topologies both as schematic diagrams and as three-dimensional images. This provides users with a more detailed and comprehensive understanding of protein structures and enables them to visualize the relationships between different topologies.
