It belongs to the group of polyphenol oxidases. Laccase is also present in plants and bacteria.Laccase from Trametes versicolor has been used: to assess the use of four laccase-producing strains in waste water treatment in laccase assay in screening the lignolsSome of the enzymatic actions of laccase are associated with sporulation, detoxification, morphogenesis, melanin polymerization and it offers protection to spore coat. Laccase can catalyse a number of substrates including medicinal drugs and halogenated pesticides. It utilizes oxygen for its catalysis. For these reasons, it might be useful in the biological degradation of micropollutants in wastewater treatment. Laccase catalyzes the oxidation of phenol containing compounds, including lignin, through the reduction of oxygen to water. The presence of mediators will allow the oxidation of non-phenlic compounds as well. The primary function of laccase is to degrade lignin in fungi...

HSPD1 may function as a signaling molecule in the innate immune system. This protein is essential for the folding and assembly of newly imported proteins in the mitochondria. It may also prevent misfolding and promote the refolding and proper assembly of unfolded polypeptides generated under stress conditions in the mitochondrial matrix. HSPD1 gene is adjacent to a related family member and the region between the 2 genes functions as a bidirectional promoter. Several pseudogenes have been associated with this gene. Mutations associated with this gene cause autosomal recessive spastic paraplegia 13. Defects in HSPD1 are a cause of spastic paraplegia autosomal dominant type 13 (SPG13). Spastic paraplegia is a degenerative spinal cord disorder characterized by a slow, gradual, progressive weakness and spasticity of the lower limbs. Defects in HSPD1 are the cause of leukodystrophy hypomyelinating type 4 (HLD4); also called mitochondrial HSP60 chaperonopathy or MitCHAP-60 disease. HLD4 is a severe autosomal recessive hypomyelinating leukodystrophy. HSPD1 is clinically characterized by infantile-onset rotary nystagmus, progressive spastic paraplegia, neurologic regression, motor impairment, profound mental retardation. Death usually occurs within the first two decades of life... Read More | Keratinocyte growth factor (KGF) is a cytokine found by Rubin et al.

(1989) from the culture supernatant of embryonic lung fibroblasts, which is a member of the FGF family, namely FGF-7. KGF is an effective epithelial-specific growth factor secreted by mesenchymal cells and distributed in epithelial cells. Its mitotic activity is mainly manifested in keratinocytes, which can specifically promote the proliferation, migration and differentiation of epithelial cells. It is closely related to organ development, wound repair, tumor genesis and immune reconstruction.Activity definition: The ED50 value is less than 1.0 ng/ml, that is, the corresponding activity unit is greater than or equal to 1 x 10*6 units/mg, as determined by the proliferation method of cultured MCF-7 cells...
