Freezing should have an effect on amylase. Amylase is an enzyme, which is therefore a protein, and has optimum conditions. Freezing it will severely slow it down, and I'm pretty sure will denature it, so yes it will completely reduce if not stop the effect of amylase. Freezing does not denature enzymes, heat does.
Low pH(HCl) amylase incubated at 100c
Enzymes from an organism are generally going to work best around the conditions that the organism tends to live. Fungi usually live in quite cool areas (think woodland) and in acidic soils. Bacteria can live anywhere generally and their optimum conditions could be anything.

The enzyme amylase is released in the mouth, referred as the salivary amylase, and in the duodenum of the small intestine by the pancreas, referred as the pancreatic amylase.
works best in neutral conditions
In the mouth, salivary amylase works to break down cooked starch into maltose. The duodenum (first part of the small intestine), pancreatic amylase works to do the same. Amylase only works in these places because they provide the optimum pH conditions for amylase to work (range from pH 6 - 8).

Amylase enzymes.
Amylase has an optimal pH range of 6.7 - 7.0 and an optimal temperature of around 37 degrees Celsius or 98.6 degrees Fahrenheit. This is what would be expected of an enzyme that needs to be in its most active form in the saliva of the mouth.
neither, caterpillars prefer warm conditions.

Ptyalin is an alpha-amylase. It is the alpha-amylase found in saliva
