Properties of a particulate chitin synthetase from Mucor rouxii.
The properties and behavior of a “microsomal” (100,000 X g particles) chitin synthetase of Mucor rouxii were investigated. The enzyme utilizes uridine diphosphate N-acetylD-glucosamine (UDP-GlcNAc) as glycosyl donor and is strongly and specifically activated by free N-acetyl-o-glucosamine (GlcNAc). A variety of GlcNAc analogues were tested as activators but were found ineffective. A small propo...
متن کاملCopper Binding by Inactivated Cells of Mucor Rouxii
Inactivated copper-sensitive and copper-tolerant strains of Mucor rouxii cultured at high copper concentration were tested for their potential to adsorb Cu(II) ions from solution. We performed batch experiments to determine the pH profile for Cu(II) binding, binding capacity and the possibility of removing the Cu(II) that had been adsorbed. The biomasses studied showed a high affinity for Cu(II...
متن کاملIsolation of chitin deacetylase from Mucor rouxii by immunoaffinity chromatography
The purification of chitin deacetylase from Mucor rouxii to homogeneity employing conventional methods has already been described. However, a lengthy protocol is required resulting in a low yield and specific activity for the enzyme . A 169-fold one-step purification of chitin deacetylase by immunoaffinity chromatography is reported, resulting in a homogeneous enzyme preparation. The enzyme pur...
متن کاملThiamine and Nicotinic Acid: Anaerobic Growth Factors for Mucor Rouxii.
Bartnicki-Garcia, S. (Rutgers, the State University, New Brunswick, N. J.), and Walter J. Nickerson. Thiamine and nicotinic acid: Anaerobic growth factors for Mucor rouxii. J. Bacteriol. 82:142-148. 1961.-Mucor rouxii requires preformed thiamine and nicotinic acid for anaerobic growth. Such requirements are not manifested during aerobic incubation. Aerobically, the fungus was shown to be able t...
متن کاملControl of dimorphism in Mucor by hexoses: inhibition of hyphal morphogenesis.
In anaerobic cultures of Mucor rouxii, morphogenesis was strongly dependent on hexose concentration as well as pCO(2). At low levels of hexose or CO(2), or both, hyphal development occurred; at high levels, the fungus developed as yeast cells. Other dimorphic strains of Mucor responded similarly to hexose and CO(2) but differred in their relative sensitivity to these agents. Glucose was the mos...
