Maltoporin lamb

WebLamB facilitates the uptake of maltose and malto-dextrinsacross thebacterial outermembraneandacts as a general porin for small molecules. Usingdirected deletion mutagenesis we removed several regions of the LamB polypeptide and identified a polypeptide loop that both constricts the maltoporin channel and binds maltodextrins. In … WebSep 1, 2002 · For many years the research of Maurice Hofnung endeavored to explain the transport of maltose and maltodextrins by LamB, also known as maltoporin.
