Porous kaolinite bead: A novel but economical solid support material for biomass in fluidised bed technology
Porous kaolinite beads were prepared by mixing kaolinite with various proportions of rice hull ash (RHA) and heating in a furnace at 800 °C for five hours. Those with 10 to 60% (w/w) RHA were very porous and h...

Regional localization of the gene coding for sphingolipid activator protein SAP-1 on human chromosome 10
Sphingolipid activator protein SAP-1 is required for the enzymatic hydrolysis of GMI ganglioside and sulfatide. The gene coding for SAP-1 was previously mapped to human chromosome 10 using monospecific antibod...

Mutational analysis in a patient with a variant form of Gaucher disease caused by SAP-2 deficiency
It is now clear that the lysosomal hydrolysis of sphingolipids requires both lysosomal enzymes and so-called sphingolipid activator proteins (SAPs). One gene, called prosaposin, codes for a precursor protein t...

Biochemical and Molecular Biological Characterization of Biotinylated Proteins of Plants
At least six biotinylated polypeptides can be detected in extracts from plants (1). These polypeptides are approximately 240 kDa, 120 kDa, 75 kDa, 60 kDa, 39 kDa and 34 kDa in size. Furthermore, the biotin enz...

Study on the Acrtion Mechanism of Hemorrhagin I from Agkistrodon acutus Venom
Up to now, studies on the receptor of neural toxins and their functional mechanism were extensively reported (Tu, 1977a). Receptors of neural toxins have been proved to be present in the animal’s cells. As to ...

Analysis of Cell Death by Flow Cytometry
Apoptosis and necrosis denote two distinct modes of cell death. The distinction is based on differences in morphological, biochemical and molecular changes that occur within the dying cell (revie...

Purification, characterization and gene sequence analysis of a novel cytochrome c co-induced with reductive dechlorination activity in Desulfomonile tiedjei DCB-1
The sulfate-reducing bacterium, Desulfomonile tiedjei DCB-1, conserves energy for growth from reductive dechlorination of 3-chlorobenzoate via halorespiration. To understand this respiratory process better, we ex...

Directional mutational pressure affects the amino acid composition and hydrophobicity of proteins in bacteria
The relationship between change in genomic GC content and protein evolution in bacteria was studied by simple correlational analysis (at the genus level) and by Felsenstein’s (1985) independent contrast test. ...

Novel Biological Process for L-DOPA Production from L-Tyrosine by P-Hydroxyphenylacetate 3-Hydroxylase
A novel biological method was developed for the production of L-3,4-dihydroxyphenylalanine (L-DOPA) from L-tyrosine by p-hydroxyphenylacetate 3-hydroxylase of Escherichia coli strain W (ATCC 11105). About 48 m...

Structure of the Bcr-Abl oncoprotein oligomerization domain
The Bcr-Abl oncoprotein is responsible for a wide range of human leukemias, including most cases of Philadelphia chromosome-positive chronic myelogenous leukemia. Oligomerization of Bcr-Abl is essential for on...

Chapter
Functional divergence in protein (family) sequence evolution
As widely used today to infer ‘:function’, the homology search is based on the neutral theory that sites of greatest functional significance are under the strongest selective constraints as well as lowest evol...

Detection of Photon Emission from Biological Systems
Since photon emission from living organisms is extremely weak (the photon flux is the order of less than 10−15 W) in comparison with a normal light source, some very sensitive methods and devices have been establ...

Cloning and localization of vip3A gene of Bacillus thuringiensis
An insecticidal protein gene, vip3A, was cloned from Bacillus thuringiensis strain WB50. The nucleotide sequence of 2,460 bp (GenBank acc. No. AY295778) showed 99% homology with the known vip3A genes. Using speci...
