Python script to analyze (shortest-path) rings in structures read from xyz-files. It can be useful for example to identify defects in crystal structures or molecules.
Tool to fetch protein/DNA truncation constructs from Uniprot DB
Very simple python script which saves you the pains of counting the amino acids/DNA bases in fasta files from the Uniprot and NCBI RefSeq Database (1, 2).
Lets say you want the amino acid sequence of range 128-387 from a 1000 amino acid protein - this script will help you to avoid counting mistakes by just showing you the specified sequence in amino acids and coding DNA base pairs (ideal for amplification primer design) of a specified Uniprot ID
