Efficient release of ligands from the Ca(2+)-dependent carbohydrate-recognition domain (CRD) of the hepatic asialoglycoprotein receptor at endosomal pH requires a small set of conserved amino acids that includes a critical histidine residue. When these residues are incorporated at corresponding positions in an homologous galactose-binding derivative of(More)
Mutations in the collagen-like domain of serum mannose-binding protein (MBP) interfere with the ability of the protein to initiate complement fixation through the MBP-associated serine proteases (MASPs). The resulting deficiency in the innate immune response leads to susceptibility to infections. Studies have been undertaken to define the region of MBP that(More)
The mechanism of oligosaccharide binding to the selectin cell adhesion molecules has been analyzed by transferring regions of the carbohydrate-recognition domains of E- and P-selectin into corresponding sites in the homologous rat serum mannose-binding protein. Insertion of two basic regions and an adjacent glutamic acid residue leads to efficient binding(More)
The mean volumes of stationary-phase cells of wild-type and asporogenous mutants of Bacillus subtilis have been measured. Mutants blocked at stage 0 of sporulation either produced cells that had the same volume as the developing sporangium or they divided to produce cells of one-half this volume. The order of expression of the genes affected by the(More)
