Recently, amylolytic activity was detected in IgMs isolated from the sera of the patients with multiple sclerosis. All purified samples of IgM were electrophoretically homogenous and did not contain any co-purified a-amylase and a-glucosidase activities, in accordance with a set

The alpha-amylase from Bacillus sp. no. 195 (BAA) consists of two domains: one is the catalytic domain similar to alpha-amylases from animals and Streptomyces in the N-terminal region; the other is the functionally unknown domain composed of an approx. 90-residue

The catalytic efficiency (kcat/Km) and the cleaved bond distribution for the nitrophenylated maltooligosaccharides, p-NPGlcn (2 < or = n < or = 7) hydrolysed by porcine pancreatic alpha-amylase isozymes I and II were determined. The subsite affinities (Ai) were calculated

Enzymatic modification at the nonreducing end D-glucosyl residue of p-nitrophenyl alpha-maltopentaoside was developed by using the transglycosylation of beta-D-galactosidase from Bacillus circulans. The enzyme regioselectively synthesized p-nitrophenyl 4(5)-O-beta-D-galactosyl-alpha-maltopentaoside (a yield of 12.0% based on the amount of p-nitrophenyl alpha-maltopentaoside added)

We describe a reagent for measuring alpha-amylase (EC 3.2.1.1) activity in serum with use of a thexyldimethylsilyl ether of p-nitrophenyl-alpha-D-maltoheptaoside (SB7) as substrate. This substrate differs from Genzyme's benzylidene-blocked p-nitrophenylmaltoheptaoside substrate (B-PNPG7). The reagent, optimized for the characteristics of the
