Mutarotase from Penicillium notatum. I. Purification, assay, and general properties of the enzyme.
In a study of the mechanism of action of notatin, the flavin adenine dinucleotide-dependent glucose aerodehydrogenase of molds, Bentley and Neuberger (2) in 1949 obtained evidence suggesting that the enzyme preparation also catalyzed the mutarotation of glucose. Keilin and Hartree (3, 4) demonstrated that some notatin samples contained a second enzyme, named mutarotase, which was the most activ...
متن کاملFrom Two Strains of Penicillium Notatum
This paper is the second of a series dealing with the analysis of penicillin by means of a chromatogram using solvent-phosphate buffer partition on a silica base. The first paper (Levi, 1948) described the development of this type of chromatogram which is based on that ofMartin & Synge (1941), and outlined the principles of its application to the study of penicillin. The work described was carr...
متن کاملSorbicillin analogues and related dimeric compounds from Penicillium notatum.
In our screening of microorganisms for new natural products, the fungus Penicillium notatum delivered further members of the sorbicillin family, namely, the sohirnones A [3, 1-(2,4-dihydroxy-5-methylphenyl)hex-4-en-1-one], B [4a, 1-(2,4,5-trihydroxy-3,6-dimethylphenyl)hexa-2,4-dien-1-one], and C [5, 1-(2,4,5-trihydroxy-3,6-dimethylphenyl)hex-4-en-1-one]. A stable tautomer of oxosorbicillinol (7...
متن کاملReminiscence of phospholipase B in Penicillium notatum
Since the phospholipase B (PLB) was reported as a deacylase of both lecithin and lysolecithin yielding fatty acids and glycerophosphocholine (GPC), there was a question as to whether it is a single enzyme or a mixture of a phospholipase A2 (PLA2) and a lysophospholipase (LPL). We purified the PLB in Penicillium notatum and showed that it catalyzed deacylation of sn-1 and sn-2 fatty acids of 1,2...
متن کاملA Comparison of Penicillin-producing Strains of Penicillium notatum-chrysogenum.
Sampling and storage. The fermentations were conducted in the 100-gallon tanks described by Stefaniak et al. (1946). Samples were removed periodically into 500-ml flasks and ifitered. A 0.5-ml filtered sample was immediately diluted for penicillin assay by addition to previously chilled phosphate buffer in volumetric flasks (4.0 g KH2P04 and 1.0 g K2HPO4 per 500 ml solution in distilled water; ...
