PIP60-1, a novel heteropolysaccharide isolated from fruiting bodies of the medicinal fungus, Phellinus igniarius, has a molecular weight of 1.71 x 10(4)Da and is composed of L-fucose, D-glucose, D-mannose, D-galactose and 3-O-Me-D-galactose in a ratio of 1:1:1:2:1. A structural investigation of PIP60-1 carried out using sugar and methylation analyses,(More)
 The ferritin of Escherichia coli (EcFtnA) is similar to human H-chain ferritin (HuHF) in having 24 subunits, each containing a dinuclear site at which two iron atoms can be oxidised (the diiron centre). In EcFtnA, unlike HuHF, fluorescence quenching of Trp122, located near site A of the dinuclear centre, can be used to monitor metal binding (this(More)
