ectoenzymes

enzymes secreted across the body wall of a SAPROPHYTE, into the materials which they have invaded, so facilitating absorption.

These esterases, also known as ectoenzymes or ectoesterases, play a mediating role in regulation of AM response to various external and internal agents [22].
We also used community ectohydrolase potentials to assess the role of bacterial ectoenzymes in the degradation of polymers in the lobster carapace.
The substrates for these ectoenzymes were leucine--methylcoumarynyl (MCA)--amide, methylumbelliferyl (MUF)-D-[micro]Lucoside, MUF-N-acetyl-D-glucosaminide, and MUF-oleate, respectively.
Given the metabolic cost of manufacturing ectoenzymes, regulation is theorized to be tightly controlled by both the availability of target substrates for hydrolysis and the scarcity of other more labile compounds to fuel productivity (Chrost 1989).
In fact, Cell wall degradation occurs not in the immediate vicinity of the hyphal sheath or out of the lumen (fig 1-8), but the ectoenzymes of the brown rot fungi must first diffuse very deeply into the cell wall through the S3 layer, to degrade the cellulose-rich S2 layer.
His experiments led him to introduce molecules called ectoenzymes into frog embryos of only eight cells.
They discovered that introducing certain ectoenzymes to cells would lead to eyes growing.
They produced tadpoles with eyes in their sides, abdomens and tails by judicious use of the right ectoenzymes.
Ectoenzymes are a kind of signalling and energy carrying molecule found in living things.

Prof Nicholas Dale of Warwick University was studying how frogs move when he put ectoenzymes into embryos which grew several eyes.
1, ACE), acting as ectoenzymes on the outer surface of different cells and included in the metabolism of regulatory peptides, like substance P, bradykinin, enkephalins, natriuretic peptides and other vasoactive hormonal peptides (Hooper, 1996).
