Dihydroxyphenylalanine (DOPA) melanins formed from tyrosine by tyrosinases are found in
microorganisms, plants, and animals. Most species in the soil-dwelling, gram-positive …

Sporothrix schenckii is the etiological agent of sporotrichosis, the main subcutaneous
mycosis in Latin America. Melanin is an important virulence factor of S. schenckii, which …

Streptomyces castaneoglobisporus HUT6202 overproduces a diffusible melanin-like
pigment. An operon, designated mel, containing a gene that encodes tyrosinase, which is …

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

A 1.5-kb genomic fragment isolated from Streptomyces avermitilis that directs the synthesis
of a brown pigment in Escherichia coli was characterized. Since pigment production in …

Glarea lozoyensis produces pneumocandin B 0, a potent inhibitor of fungal glucan
synthesis. This industrially important filamentous fungus is slow-growing, is very darkly …

A 30-kDa novel tyrosinase was purified to homogeneity. The K m for L-Dopa and L-tyrosine
were determined as 0.42 and 0.25 mM. The 1231 bp (base pair) mel C gene and its 167 bp …

Melanins are chemically diverse ubiquitous pigments found across the life forms
synthesized via different biochemical pathways mainly from L-tyrosine or acetyl CoA …

An albino mutant of Thielaviopsis basicola metabolized scytalone, vermelone, and 1, 8-
dihydroxynaphthalene to melanin like that in the wild-type fungus. The melanin appeared as …

Melanin biosynthesis was studied in 26 species of fungi belonging to 16 genera using the
melanin inhibitor tricyclazole (5-methyl-1, 2, 4-triazolo (3, 4 b)-benzothiazole) and enzyme …
