Endohydrolysis of (1→3)- or (1→4)-linkages in β-D-glucans when the glucose residue whose reducing group is involved in the linkage to be hydrolysed is itself substituted at C-3 Substrates include laminarin , lichenin and cereal D - glucans .
The addition of 0.1 M 2-mercaptoethanol highly increases enzyme activity against glycoproteins containing inter- or intra-molecular disulfide bridges, unlike detergents like Triton X-100, n- Octylglucoside, or zwitterionic detergents.

Mannan endo-1,6-α-mannosidase (EC 3.2.1.101, exo-1,6-β-mannanase, endo-α-1→6-D-mannanase, endo-1,6-β-mannanase, mannan endo-1,6-β-mannosidase, 1,6-α-D-mannan mannanohydrolase) is an enzyme with systematic name 6-α-D-mannan mannanohydrolase. [1] [2] [3] It catalyses the random hydrolysis of (1→6)-α-D-mannosidic linkages in unbranched ...
A vesicle is a relatively small, membrane-enclosed sac that stores or transports substances. [6] The cell membrane is a protective barrier that regulates what enters and leaves the cell. [ 7 ] There is also an organelle known as the Spitzenkörper that is only found in fungi, and is connected with hyphal tip growth.
2010: Endo acquired generic manufacturer Qualitest Pharmaceuticals for $1.2 billion [8] 2011: Endo acquired medical device manufacturer American Medical Systems for more than $2 billion [18] [19] [7] 2013: Endo agreed to purchase Paladin Labs Inc for about $1.6 billion to gain access to the Canadian market as well as expand into emerging markets.
In Coxeter notation can be represented as [6,4 *], removing two of three mirrors (passing through the square center) in the [6,4] symmetry. The *3333 symmetry can be doubled to 663 symmetry by adding a mirror bisecting the fundamental domain.
The spontaneous dimerization of neat cyclopentadiene at room temperature to form dicyclopentadiene proceeds to around 50% conversion over 24 hours and yields the endo isomer in better than 99:1 ratio as the kinetically favored product (about 150:1 endo:exo at 80 °C). [6] However, prolonged heating results in isomerization to the exo isomer.
