sentence: Dhbs are often found in ribosomally synthesized and post-translationally modified peptides ( RiPPs ) , e.g ., in thiopeptides such as cyclothiazomycin [ 28 ] or in depsipeptides such as tumescenamides [ 29 ] , but also in peptides synthesized by NRPS , e.g ., in albopeptin or in the recently discovered malpinins [ 30,31 ] .
