Protein tyrosine phosphatases in disease processes
(Elsevier, 1994-12)
Given the importance of tyrosine phosphorylation of proteins in signalling pathways, it is perhaps not surprising that protein tyrosine phosphatases (PTPs) are involved in the pathogenesis of certain human diseases. A PTP ...
Significance of Root-Mean-Square Deviation in Comparing Three-dimensional Structures of Globular Proteins
(Elsevier, 1994-01-13)
In the study of globular protein conformations, one customarily measures the similarity in three-dimensional structure by the root-mean-square deviation (RMSD) of the C[alpha] atomic coordinates after optimal rigid body ...
Localization of the dopamine transporter gene, Dat1 , on mouse Chromosome 13
(Springer-Verlag, 1994-02)
Capacity for microtubule reorganization and cell wall synthesis in cytoplasts of the green alga Mougeotia
(Springer-Verlag, 1994-03)
A small proportion of nucleate subprotoplasts (karyoplasts) and enucleate subprotoplasts (cytoplasts) are formed during the preparation of protoplasts from the filamentous green alga Mougeotia . Regeneration of Mougeotia ...
Tidal freshwater wetland zonation: seed and seedling dynamics
(Elsevier, 1994-01)
Zonation patterns of seed rain (input), persistent seed bank (seeds persisting for 1 year or longer), field seedlings, and seed production were studied in a New Jersey tidal freshwater wetland along transects extending ...
A Myosin from a Higher Plant has Structural Similarities to Class V Myosins
(Elsevier, 1994-06-16)
In plant cells, myosin is believed to be the molecular motor responsible for actin-based motility processes such as cytoplasmic streaming and directed vesicle transport. In an effort to characterize plant myosin, a cDNA ...
Effects of host switching on gypsy moth ( Lymantria dispar (L.)) under field conditions
(Springer-Verlag, 1994-03)
Effects of various single and two species diets on the performance of gypsy moth ( Lymantria dispar (L.)) were studied when this insect was reared from hatch to population on intact host trees in the field. The tree species ...
Light-Activated Release of Nitric Oxide from Vascular Smooth Muscle of Normotensive and Hypertensive Rats
(Elsevier, 1994-04-15)
A porphyrinic sensor was used to monitor nitric oxide release from vascular smooth muscle in response to exposure to ultraviolet light. Aortic rings exposed to UV light relaxed with a time course that parallels this observed ...
Crystal Structure of Escherichia coli Thioredoxin Reductase Refined at 2 A Resolution : Implication for a Large Conformational Change during Catalysis
(Elsevier, 1994-02-24)
The crystal structure of three forms of Escherichia coli thioredoxin reductase have been refined: the oxidized form of the wild-type enzyme at 2[middle dot]1 A resolution, a variant containing a cysteine to serine mutation ...
Tyrosine Kinase Inhibitors Attenuate "Capacitative" Ca2+ Influx in Rat Pancreatic Acinar Cells
(Elsevier, 1994-08-15)
The effect of several tyrosine kinase inhibitors was tested on Ca2+ influx mediated by thapsigargin-and CCh-induced intracellular store depletion. Genestein inhibited Ca2+ influx in a concentration dependent manner without ...
