Rhomboids are ubiquitous proteins with unknown roles in mycobacteria. However, bioinformatics suggested putative roles in DNA replication pathways and metabolite transport. Here, mycobacterial rhomboid-encoding genes were characterized; first, using the Providencia stuartii null-rhomboid mutant and then deleted from Mycobacterium smegmatis

Multi-drug-resistant infections caused by Gram-negative pathogens are rapidly increasing, highlighting the need for new chemotherapies. Unlike Gram-positive bacteria, where many different chemical classes of antibiotics show efficacy, Gram-negatives are intrinsically insensitive to many antimicrobials including the macrolides, rifamycins, and aminocoumarins
