Inhibition kinetics of green crab (Scylla serrata) alkaline phosphatase activity by dithiothreitol or 2-mercaptoethanol

Improvement of innate immune responses and defense activity in mitten crab (Eriocheir sinensis) by oral administration of β-glucan

“…The reason for the inconsistent results was probably due to the differences in species or the non-sensitivity of ACP in crab to BG. As for ALP, Zhang et al (2000) reported that it was a key enzyme participating in cell phosphate metabolism, which was concerned with the growth and the survival of the green crab (Scylla serrata). In this experiment, ALP activity was enhanced by BG, which was in agreement with the increasing growth.…”

“…However, compared with the extensive studies on fish and shrimp, researches pertaining to the use of immunostimulants in crab health management are limited. There are few reports about application of BG in diet on mitten crab culture (Zhang et al 2000). The purpose of the present study was designed to explore the effects of BG on the growth and immune response in mitten crab, as well as on the resistance against Vibrio mimicus.…”

Heterosis of haemolymph analytes of two geographic populations in Chinese shrimp Fenneropenaeus chinensis

“…Similar to ACP, ALP was a kind of phosphomonoesterase to detoxify during the normal living and phagolysis and to digest and absorb many nutriments [15]. Zhang et al [16] reported that ALP in Scylla serrata participated in the metabolism of phosphoesterase, absorption of Ca and P and moult reaction.…”

Inhibitory kinetics of bromacetic acid on β-N-acetyl-d-glucosaminidase from prawn (Penaeus vannamei)

“…For the slow, reversible and non-competitive inhibition with fractional residue activity, the kinetic model of the enzyme reacting with the substrate and the inhibitor can be written as [23]:…”
