4.2.1. In Silico Characterization of the M. Pendans Compounds

The characteristics of compounds 1–8 were confirmed using two online software applications. The chemical structures of the four M. pendans compounds were converted using a ChemDraw in the CDX file format. The 3D structure of the MOL file for all compounds was retrieved from the PubChem Compound database. Those MOL files were used to convert the chemical structure into a 3D format using OPEN BABEL 2.4.1 program, in PDB file format [41]. The 3D structure model of PBP (PDB code: 6BSQ), SrtA (PDB code: 2KW8), DNA gyrase (PDB code: 4KSG), RNA polymerase, subunit alpha (PDB code: 1BDF), ClyM (PDB code: 5DZT), and PgrX (PDB code: 2AW6) were retrieved from Protein Data Bank. Meanwhile, others were retrieved from UniProt. They are MurB (UniProt ID: {"type":"entrez-protein","attrs":{"text":"Q830P3","term_id":"47605862","term_text":"Q830P3"}}Q830P3), RNA polymerase subunit beta (UniProt ID: {"type":"entrez-protein","attrs":{"text":"Q82Z41","term_id":"41017979","term_text":"Q82Z41"}}Q82Z41), ribosomal subunit 30S (UniProt ID: {"type":"entrez-protein","attrs":{"text":"Q82ZI6","term_id":"41017833","term_text":"Q82ZI6"}}Q82ZI6), ribosomal subunit 50S (UniProt ID: {"type":"entrez-protein","attrs":{"text":"Q839E6","term_id":"81585510","term_text":"Q839E6"}}Q839E6), FsrB (UniProt ID: G8ADN9), and GBAP (UniProt ID: G8ADP0), which were built using the SWISS-MODEL server (https://swissmodel.expasy.org/, accessed on 8 May 2020) in PDB file format [42].
