To investigate the mechanism of interaction of the toxin colicin E1 with membranes, three cysteine substitution mutants and the wild type of the channel-forming fragment were spin labeled at the unique thiol. Time-resolved interaction of these labele

The molecularity of the ion channel formed by peptide fragments of colicin has taken on particular significance since the length of the active peptide has been shown to be less than 90 amino acids and the lumen size at least 8 A. Cell survival experi

An algorithm is presented for calculating the solvent accessible surface area of proteins using a three-dimensional grid. Since it requires only calculations based on single atomic positions, the algorithm is easy to be vectorized. It has been implem

We describe the design, construction, and performance of a special purpose, hardwired accelerator for molecular mechanical calculations called FASTRUN. The processor was designed at Columbia University in 1984, constructed in the Instrumentation Divi

The paper describes the history of tracing activities in the Levinthal lab from 1965 to the present. It also focuses on the evolution of electron micrograph (EM) tracing from early hand tracing reconstruction to the current, nearly fully automated CA

Graph theory methods were used to analyze the topology of the renal glomerular capillary network using data both from a serial reconstruction of a rat glomerulus and from the literature. The graphs obtained were tested for planarity, and all but one

To search for genes involved in determining the morphology of individual neuronal types, a cDNA library was constructed from postnatal day 13 mouse cerebellum. From this library, 2 clones, L7 and L19, were isolated by a differential hybridization pro

Colicin E1 is an E. coli plasmid-encoded water-soluble protein that spontaneously inserts into lipid membranes to form a voltage-gated ion channel. We have employed a novel approach in which site-directed mutagenesis is used to provide highly specifi
