Solomon E. Dedeyan B. Two of the sites, at positions andseem less likely to be glycosylated because of proline at C-terminal side of threonine [ 22 ]. Molecular analysis of a laccase gene from the white rot fungus Pycnoporus cinnabarinus. The von Heijne signal sequence prediction [ 20 ] was used to predict the start of the mature laccase. Calvo A.
Computer searches of the databases identified the sequence of each of the PCR products analyzed as a laccase gene sequence, suggesting the specificity of.

The corresponding laccase cDNA was identical to the genomic sequence except for 10 introns that were 50 to 60 bp long. A sequence analysis indicated that. Three laccase genes: lcc1, lcc2 and lcc3 have been cloned and sequenced from this DNA are fully confirmed by match analysis with our cDNA sequences.
NG carried out the molecular biological studies leading to elucidation of the complete cDNA sequence and expression of the enzyme in P. Felsenstein J. The sequence also showed the presence of pre-sequence in agreement with its extracellular localization.
As observed, the rLac produced in P. Modelling and structural relationships.

Automatic assertion according to sequence analysisi. Amino acid sequence alignment of laccase from Cyathus bulleri with other fungal laccases. Cerrena maxima (PDB accession code 2H5U_A).
A second laccase gene, CVLG1, was isolated from Coriolus versicolor. The determined nucleotide sequences were analyzed on a computer.
Light grey: nLac, Dark grey: rLac. At culture OD of 2—6, the cells were harvested by centrifugation and re-suspended in buffered complex methanol medium at an OD of 1. The author SM acknowledges the financial assistance received from Dept. The experiments were performed either in a glass cuvette or in a Microtiter plate reader Infinite M, Tecan for multiple laccase measurements.

|Tryptic finger print analysis of the nLac and the rLac indicated altered glycosylation patterns.
Hullo M. The blue boxes represent the cysteine residues present in disulphide bridges.
Evolutionary and structural diversity of fungal laccases. Interestingly, both the rLac and the nLac were equally unstable in THF solvent of a higher log P value which is likely to have distorted the enzyme hydration and distort the conformation leading to a drastic decrease in enzyme activity.
As reported by Kumar. Using cDNA sequence analysis, the open reading frame size of laccase genes fvLac-1, fvLac-2, fvLac3, and fvLac-4 were estimated to be.
The gene, protein and glycan structures of laccase from Pleurotus ostreatus. The sequence also showed the presence of pre-sequence in agreement with its extracellular localization. All authors have read and approved the manuscript.
Organic solvent tolerance was also measured in a similar manner for the purified nLac. Residual activity of laccase in the presence of NaCl concentration.
