Mucopolysaccharidosis IV A: assignment of the human N-acetylgalactosamine-6-sulfate sulfatase
(GALNS) gene to chromosome 16q24.
Melatonin downregulates some of the enzymes necessary for the synthesis of estrogens, such as aromatase (cytochrome P450), steroid sulfatase
(STS), and 17b-hydroxysteroid dehydrogenase type 1 (17[beta]-HSD1), whereas it stimulates estrogen sulfotransferase (EST), the enzyme that inactivates estrogens.
The HLADR-presented GNS peptide has marked sequence homology with epitopes from sulfatase
proteins of the Prevotella sp.
X-linked ichthyosis (XLI) is an X-linked recessive disorder with a prevalence of approximately 1:4,000, demonstrating dry, scaly skin due to a deficiency of the enzyme steroid sulfatase
Lack of sulfatase
enzyme would remove the GAGS from dentinal tubule site which can cause lack of integration at enamel dentinal junction.
Then 75 [micro]L of aryl sulfatase
(E.C.22.214.171.124) type H1 from Helix pomatia (Sigma-Aldrich, Taufkirchen, Germany) was loaded into each column, followed by a desulfation reaction overnight (16-18 hours) at room temperature.
The internal standards were deconjugated using 5 [micro]L of [beta]-glucuronidase/sulfatase from Helix pomatia (Type HP-2, aqueous solution, [beta]-glucuronidase activity [greater than or equal to] 100000 units/mL, sulfatase
activity [less than or equal to] 7500 units/mL, Sigma-Aldrich, USA).
Most of the excreted indoxyl sulfate is digested into indoxyl by indoxyl sulfatase
produced by certain bacteria.
One portion of the samples was processed and analysed immediately for biological attributes: microbial biomass carbon ([C.sub.mic]) and N ([N.sub.mic]), mineralisable C ([C.sub.min]) and N ([N.sub.min]), dehydrogenase activity, fluorescein diacetate hydrolysing activity (FDHA), [beta]-glucosidase activity, aryl sulfatase
activity, acid and alkaline phosphatase activity, and urease activity.
vulnificus produce diversity of destructive extracellular products including elastase, protease, hemolysin, collagenase, DNase, lipase, phospholipase, mucinase, chondroitin sulfatase
, hyaluronidase and fibrinolysin (Wright & Morris, 1991; Al-Assafi et al., 2014).
