High impact information on Emericella

• Glutamine synthetase type I (GSI) genes have previously been described only in prokaryotes except that the fungus Emericella nidulans contains a gene (fluG) which encodes a protein with a large N-terminal domain linked to a C-terminal GSI-like domain [1].
• 5'-Hydroxyaverantin (HAVN) was isolated from a mold, Emericella heterothallica IFO 30842 [2].
• Emericella venezuelensis produces aflatoxin B1, sterigmatocystin, and terrein and compounds with chromophores of the shamixanthone, emerin and desertorin type of compounds [3].
• Since three species of Emericella have stellate ascospores, and the type material of E. variecolor is equivocal, this species is epitypified with CBS 598.65 [3].

Chem. 275:39894-9) and to new current-voltage-time records from Xenopus oocytes with functionally expressed NrtA (crnA) 2H+-NO3- symporter from Emericella (Aspergillus) nidulans [4].

Associations of Emericella with chemical compounds

• Falconensones A and B are new type of yellow pigment isolated from the mycelial extract of ascomycetous fungi, Emericella falconensis or Emericella fruticulosa, whose structures are similar to retinoic acid (RA) [5].
• In beta-lactam-antibiotic-producing fungi, such as Aspergillus (Emericella) nidulans, L-alpha-aminoadipic acid is the branching point of the lysine and penicillin biosynthesis pathways [6].
• Structures of novel epipolythiodioxopiperazines, emethallicins B, C, and D, potent inhibitors of histamine release, from Emericella heterothallica [7].
• Inhibition of mitochondrial respiration by asteltoxin, a respiratory toxin from Emericella variecolor [8].
• Evariquinone, isoemericellin, and stromemycin from a sponge derived strain of the fungus Emericella variecolor [9].

Gene context of Emericella

• This gene product shows significant sequence similarity to PalBp, a fungal (Emericella nidulans) calpain-like protease that is responsible for adaptation under alkaline conditions, both in the protease domain and the domain following the protease domain [10].
• An extract from the fungus Emericella aurantiobrunnea was found to compete with macrophage inflammatory protein (MIP)-1alpha for binding to human CCR5 in a scintillation proximity assay (SPA) [11].
• Histoplasma capsulatum produces an extracellular catalase termed M antigen, which is similar to catalase B of Aspergillus and Emericella species [12].
• Vitamin C (1.0 mg ml(-1)) prevented oxidative cell injuries triggered by 0.004 U GOX in Emericella nidulans cultures but bovine liver catalase was ineffective even at a GOX : catalase activity ratio of 0.004 : 200 U [13].
• Using these primers, 426 bp fragments of a mitochondrial (mt) cytochrome b gene were amplified by polymerase chain reaction (PCR), directly sequenced, and compared among Aspergillus fumigatus, A. flavus, A. niger, A. terreus and Emericella nidulans [14].
