Dna uptake
WebDNA uptake in most systems is not sequence-specific. However, in some Gram-negative microorganisms,such as Haemophilus influenzae 12 and Neisseria species13,effi-cient uptake occurs only if a specific sequence is present, although the DNA binding is nonspecific.The sequence motifs that are required for efficient uptake,called DUS (DNA … WebJan 18, 2024 · The competence pili of transformable Gram-positive species form a subset of the diverse and widespread class of extracellular filamentous organelles known as type IV pili (T4P). In Gram-negative bacteria, T4P act through dynamic cycles of extension and retraction to carry out diverse activities including attachment, motility, protein secretion, …

Our results suggest a model whereby DNA-uptake pili function to promote inter-bacterial interactions during surface colonization.
