Biosynthesis of bacterial spore coats

Journal of Molecular Biology, 1968
Abstract The biochemical events associated with the assembly of bacterial spore coat proteins have been studied. Pulse-chase experiments using a variety of labeled amino acids have shown that coat precursor protein synthesis begins at the cessation of growth when sporulation commences (early forespore), but several hours prior to the appearance of ...

Preparation of spore coats ofFusarium culmorum

Experientia, 1966
Se especifican las condiciones optimas para la preparation de paredes celulares de macroconidios deFusarium culmorum, utilizando el desintegrador de Mickle y se demuestra la pureza de las preparaciones mediante su examen al microscopio de fase y electronico.

Enzyme‐driven bacillus spore coat degradation leading to spore killing

Biotechnology and Bioengineering, 2013
ABSTRACTThe bacillus spore coat confers chemical and biological resistance, thereby protecting the core from harsh environments. The primarily protein‐based coat consists of recalcitrant protein crosslinks that endow the coat with such functional protection.

Formation of the Dictyostelium spore coat

Developmental Genetics, 1990
AbstractThe spore coat forms as a rigid extracellular wall around each spore cell during culmination. Coats purified from germinated spores contain multiple protein species and an approximately equal mass of polysaccharide, consisting mostly of cellulose and a galactose/N‐acetyl‐galactosamine polysaccharide (GPS).

Properties of Bacillus cereus spore coat mutants

Journal of Bacteriology, 1975
Two classes of spore mutants have been selected in Bacillus cereus T, those producing lysozyme-sensitive spores, and those producing spores dependent upon lysozyme for germination. One mutant from each class was studied in detail and found to have defective packing of the spore coat layers.

Germinability of coat-lacking spores of Bacillusmegaterium

Biochemical and Biophysical Research Communications, 1985
Upon treatment with acid, the germinability of both intact and coat-lacking spores of Bacillus megaterium ATCC 19213 exhibited similar features. Namely, when the spores previously germinated by alanine in the presence of phosphate buffer were converted to H-spores by treatment with nitric acid, germination proceeded at a very low speed in a same ...

Hexapeptide repeat structure in dictyostelium spore coat protein

Biochemical and Biophysical Research Communications, 1986
The sequences of the NH2-termini of two spore coat proteins of Dictyostelium discoideum have been determined. One of them (SP60) consists of perfect hexapeptide repeats of the sequence Gly-Asp-Trp-Asn-Asn-Asx-. The sequence has some homology to the parvovirus capsid protein which does not display periodicity.

Genes encoding spore coat polypeptides from Bacillus subtilis

Journal of Molecular Biology, 1987
Endospores of the Gram-positive bacterium Bacillus subtilis are encased in a tough protein shell, known as the coat, that consists of a dozen or more different polypeptides. We have cloned structural genes designated cotA, cotB, cotC and cotD that encode spore coat proteins of Mr 65,000, 59,000, 12,000 and 11,000, respectively.

Studies of the spore coats of fungi I. Isolation and composition of the spore coats of Aspergillus oryzae

Biochimica et Biophysica Acta (BBA) - Specialized Section on Mucoproteins and Mucopolysaccharides, 1964
Spore coats of Aspergillus oryzae have been mechanically isolated. They exhibited a complex chemical composition consisting of polysaccharide (mannose, glucose, galactose and glucosamine), phosphate, protein and nucleic acid. Spore coats were partially hydrolyzed by the lytic enzyme from Bacillus circulans, and glucose, laminaribiose and other unknown ...

Plasma membrane proteins ofDictyostelium: The spore coat proteins

Developmental Biology, 1979
Spore coats were isolated following germination ofDictyostelium discoideum spores. They were found to contain five major proteins of apparent molecular weights of 60,000 (SP60), 68,000 (SP68), 70,000 (SP70), 96,000 (SP96), and 200,000 (SP200). Of these SP68 and SP96 were found to be glycoproteins.
