Supplementary data for: enzymic recognition of amino acids drove the evolution of primordial genetic codes

This repository contains sequence metadata, fasta files, BEAST 2 xml files, and phylogenetic trees for our aminoacyl-tRNA synthetase (AARS) analyses.

Main article: Enzymic recognition of amino acids drove the evolution of primordial genetic codes.

Contents

• accessions.tsv: AARS sequence metadata

Sequence only trees:

• class1.fasta and class2.fasta: alignment of all the common elements of the Class I and II catalytic domains
• class1.xml and class2.xml: BEAST 2 input files. Requires BEAST 2.7.5, with the OBAMA and BICEPS packages installed
• class1.nexus and class2.nexus: maximum clade credibility trees from these XML files

Insertion module + sequence trees:

• class1.im.xml and class2.im.xml: BEAST 2 input files. Requires BEAST 2.7.5, with the OBAMA, BICEPS, and IndelDollo packages installed
• class1.im.nexus and class2.im.nexus: maximum clade credibility trees from these XML files
