Directed evolution of unspecific peroxygenase from Agrocybe aegerita.
Unspecific peroxygenase (UPO) represents a new type of heme-thiolate enzyme with self-sufficient mono(per)oxygenase activity and many potential applications in organic synthesis. With a view to taking advantage of these properties, we subjected the Agrocybe aegerita UPO1-encoding gene to directed evolution in Saccharomyces cerevisiae. To promote functional expression, several different signal p...
متن کاملPyridine as novel substrate for regioselective oxygenation with aromatic peroxygenase from Agrocybe aegerita.
Agrocybe aegerita peroxidase (AaP) is a versatile extracellular biocatalyst that can oxygenate aromatic compounds. Here, we report on the selective oxidation of pyridine (PY) yielding pyridine N-oxide as sole product. Using H(2)(18)O(2) as co-substrate, the origin of oxygen was confirmed to be the peroxide. Therefore, AaP can be regarded as a true peroxygenase transferring one oxygen atom from ...
متن کاملIsolation and Identification of Mushroom Pathogens from Agrocybe aegerita
Agrocybe aegerita is an important mushroom cultivated in Korea, with good feel and a peculiar fragrance. A. aegerita can be cultivated throughout the year using culture bottles but is more susceptible to contamination than other mushrooms. Twenty-two pathogens were isolated from the fruiting bodies and compost of A. aegerita, and seven isolates were isolated from Pleurotus ostreatus to compare ...
متن کاملAn antitumour lectin from the edible mushroom Agrocybe aegerita.
An antitumour lectin (named AAL) consisting of two identical subunits of 15.8 kDa was isolated from the fruiting bodies of the edible mushroom Agrocybe aegerita using a procedure which involved precipitating the extract by addition of (NH(4))(2)SO(4), ion exchange chromatography on DEAE-Sepharose Fast Flow, gel filtration chromatography on Sephacryl S-200 HR and finally purification on a GF-250...
متن کاملCrystallization of a 45 kDa peroxygenase/peroxidase from the mushroom Agrocybe aegerita and structure determination by SAD utilizing only the haem iron.
Some litter-decaying fungi secrete haem-thiolate peroxygenases that oxidize numerous organic compounds and therefore have a high potential for applications such as the detoxification of recalcitrant organic waste and chemical synthesis. Like P450 enzymes, they transfer oxygen functionalities to aromatic and aliphatic substrates. However, in contrast to this class of enzymes, they only require H...
