May have a role in cell wall processes (PubMed:26177502). Does not exhibit cutinase activity (PubMed:19225166). Expressed at late exponential and stationary phases, but not in the early exponential phase. A single nucleotide (T) insertion is observed in the Rv3724/cut5 gene. Cut5 is expressed as Rv3724a/cut5a and Rv3724b/cut5b in H37Rv strain. Belongs to the cutinase family.
