TLDR
It is concluded that chitinase is synthesized in the microsomal fraction, accumulated in the zymogen granules and released into the cytoplasm from which it then passes into the glandular lumen across the cellular membrane.About:

Digestibility of chitin in cod, Gadus morhua , in vivo
TL;DR: The level of enzyme activity in different parts of the digestive tract was shown to be dependent on the phase of the digestion process and chitin digestion in these fish was calculated to have been 90%.

Characterization of gastrointestinal chitinase in the lizard Sceloporus undulatus garmani (Reptilia: Phrynosomatidae).
TL;DR: Chitinase activity was characterized in a second New World taxon, Sceloporus undulatus garmani, a New World, phrynosomatid lizard, and the localization of chitinolytic activity in S. u.

Transport of amylase across the apical membrane of the pancreatic exocrine cells. Quantitative analysis of zymogen granules.
Guy Dandrifosse,Léon J. Simar +1 more
TL;DR: In this article, the number or the size of the zymogen granules was calculated in a determined volume slice of pigeon pancreas and in a total cellular fraction of ZYGM granules isolated from a part of this organ having the same volume.

Mechanism of amylse secretion by the pancreas of the pigeon
TL;DR: The results suggest that pH 4-fraction amylase is the secreted enzyem and the intracellular pathway of secreted pancreatic proteins is secreted through the intact cellular membrane.

Uptake of radioactive alanine in vitro into the proteins of rat liver fractions.
TL;DR: Preliminary experiments indicated that a correlation exists between uptake of the labeled amino acid into protein and oxidative phosphorylation and a synergistic action of two fractions is necessary in order that the label be incorporated.

The fine structure of the gastric mucosa in the bat.
Susumu Ito,Robert J. Winchester +1 more
TL;DR: The fine structure of the various cell types in this species is fundamentally similar to that of the corresponding cell types of other mammals, but the relative cell numbers and distribution are somewhat different.

Synthesis and Transfer of Amylase in Pigeon Pancreatic Microsomes
TL;DR: The system in vitro comprises the vectorial mechanism involved in the transfer of newly synthesized secretory protein across the endoplasmic reticulum membrane into the cisternal space.
