Introduction
From the authors' description,The ARB (ARB short for the Latin ''arbor'') program package comprises a variety of directly interacting software tools for sequence database maintenance and analysis controlled by a commonThe latest version of the software was released in 2021. The newer version can run ongraphical user interface A graphical user interface, or GUI, is a form of user interface that allows user (computing), users to human–computer interaction, interact with electronic devices through Graphics, graphical icon (computing), icons and visual indicators such ....

By convention, the primary structure of a protein is reported starting from the amino-terminal (N) end to the carboxyl-terminal (C) end. Protein biosynthe ...data. Additional descriptive data can be stored in database fields assigned to the individual sequences or linked via local or worldwide networks. A phylogenetic tree visualized in the main window can be used for data access and visualization. The package contains additional tools for data import and export, sequence alignment, primary andsecondary structure Protein secondary structure is the local spatial conformation of the polypeptide backbone excluding the side chains. The two most common Protein structure#Secondary structure, secondary structural elements are alpha helix, alpha helices and beta ...editing, profile and filter calculation, phylogenetic analyses, specific hybridization probe design and evaluation, and other components for data analysis.
