    Gliding motility and host-cell invasion by apicomplexan parasites depend on cell-surface adhesins that are translocated via an actin-myosin motor beneath the membrane. The current model posits that fructose-1,6-bisphosphate aldolase (ALD) provides a critical link between the cytoplasmic tails of transmembrane

    Nonribosomal peptide synthetases (NRPSs) produce many important and structurally complex natural products. Because of their architectures, reprogramming NRPSs has long been attempted to access new bioactive compounds. However, detailed characterization of NRPS catalysis and substrate selectivity by adenylation (A) domains
