Tyrosinases from various organisms are compared with respect to enzymatic structure,
primary, secondary and tertiary structure, domain structure, Cu binding sites, maturation …

Tyrosinases are nearly ubiquitously distributed in all domains of life. They are essential for
pigmentation and are important factors in wound healing and primary immune response …

Streptomycetes are Gram-positive bacteria with a unique capacity for the production of a
multitude of varied and complex secondary metabolites. They also have a complex life cycle …

Tyrosinases with different physico-chemical properties have been identified from various
bacterial phyla such as Actinobacteria and Proteobacteria and their production is often …

Forty-five bacterial strains that produced diffusive pigments were isolated from 40 soil
samples. Maximum pigment production was from a Streptomyces kathirae strain designated …

In the present study different actinomycete strains were collected and isolated from Algerian
Sahara soil with the aim to select novel enzymes with promising features for …

The present study found that the n-hexane extract of freeze-dried sake lees inhibits
tyrosinase activity and showed that the constituents isolated from the n-hexane extract are …

Melanin pigment synthesized by microorganisms during hydroxylation and polymerization of
organic compounds, was an attractive choice for commercial scale production. In this study …

The relationship between l-tyrosine catabolism and melanin formation was studied in the
Vibrio cholerae strains ATCC 14035 and CECT 557. It is shown that both strains degrade l …

The identity of the product of the melA gene from Shewanella colelliana with the enzyme p-
hydroxyphenylpyruvic dioxygenase is shown. Cloning of the melA gene endowed …
