Purification and Characterization of Leech Hyaluronic Acid-endo- P-glucuronidase*
In 1960, Linker, Meyer, and Hoffman (1) reported that a crude leech preparation hydrolyzes the glucuronide linkages of hyaluronic acid, unlike bacterial and testes hyaluronidases, which act on glucosaminide linkages. This paper deals with the first systematic attempt to purify the leech P-glucuronidase that specifically hydrolyzes hyaluronic acid. Purified preparations of the enzyme have indeed...

The extraction and purification process of HA from vitreous humour of fish, among other biological materials, is based on the succession of: 1) a step of protein electrodeposition, prev...
متن کاملExtraction, Purification, and Characterization of Trypsin Obtained from the Digestive System of Yellowfin Seabream (Acanthopagrus latus)
The development of the marine aquaculture industry has led to the generation of significant amounts of fish wastes. Marine farm wastes exert adverse effects on the surrounding area of the cages. On the other hand, wastes of fish and other aquatic animals are regarded as major sources of valuable natural bioactive compounds, including enzymes, proteins, bioactive peptides, oil, amino acids, coll...
متن کاملextraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties
آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
15 صفحه اولPhosvitin kinase from the liver of the rooster. Purification and partial characterization.
Phosvitin kinase, the enzyme that phosphorylates the egg yolk protein phosvitin, has been purified more than SOOO-fold from the supernatant of rooster liver, a tissue that synthesizes phosvitin only after estrogen administration. The purified enzyme prepared from the estrogen-treated liver was recovered in high yield (49%) and was very stable at 04”. It sedimented in sucrose as a single peak wi...
