| hypocrea peltata: a mycological dr jekyll and mr hyde? | hypocrea peltata (pezizomycotina, hypocreales, hypocreaceae) is a common, widespread essentially subtropical species, with an uncharacteristically large stroma and asci containing four large and four small bicellular ascospores. its only anamorph consists of indehiscent aleuriospores; it does not form a trichoderma anamorph, which is typical of most trichoderma/hypocrea species. hypocrea peltata grows very well at 37 c. the large stromata and failure to form a trichoderma anamorph could lead one ... | 2011 | 21262986 |
| fungal metabolites. xv. primary structures of antibiotic peptides, hypelcins b-i, b-ii, b-iii, b-iv and b-v, from hypocrea peltata. application of electrospray mass spectrometry and electrospray mass spectrometry/mass spectrometry. | hypelcin b is a mixture of antibiotic peptides produced by hypocrea peltata. hypelcins b-i, b-ii, b-iii, b-iv and b-v are components of this mixture purified by reversed-phase high-performance liquid chromatography. the amino acid sequences of these peptides were determined by electrospray mass spectrometry and electrospray mass spectrometry/mass spectrometry. the molecular weights of these peptides were all ca. 2000 and the structures were very similar. | 1994 | 8069957 |
| ion-channels formed by hypelcins, antibiotic peptides, in planar bilayer lipid membranes. | ion-channel properties of native hypelcins (hp) a-i, a-v and b-v isolated from hypocrea peltata and a synthetic analog, hp-a-pheol, were studied in planar bilayer lipid membranes by a single-channel recording technique. the native and synthetic hypelcins formed ion-channels with three conductance levels for 3 mole dm(-3) kcl: < or = 0.09 ns at 225 mv (level 0, only detectable at voltages above 200 mv), approximately 0.6 ns at 150 mv (level 1, most common level) and approximately 3 ns at 150 mv ( ... | 1997 | 9188799 |
| fungal metabolites. ix. synthesis of a membrane-modifying peptide, hypelcin a-iii, from hypocrea peltata. | a membrane-modifying peptide antibiotic having uncoupling activity on rat liver mitochondria, hypelcin a-iii, has been synthesized by assembling five peptide fragments via the n,n'-dicyclohexylcarbodiimide method. the synthesized hypelcin a-iii was identical with the natural product. | 1993 | 8293518 |
