Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

Trypsin/alpha-amylase inhibitor CMx1/CMx3 is a protein that interacts with and inhibits trypsin and alpha-amylase enzymes. These enzymes play roles in digestion breaking down proteins and starches respectively. The inhibitor has alternate names such as CMx1 and CMx3 and it is expressed predominantly in the seeds of certain leguminous plants such as cereals and pulses. The known mass of CMx1/CMx3 is approximately 16 kDa.

Biological function summary

Trypsin and alpha-amylase inhibitor CMx1/CMx3 regulates the activity of digestive enzymes. It forms part of a defensive mechanism in plants against herbivores by hindering the digestion of proteins and carbohydrates in the herbivores' gut. CMx1/CMx3 works by binding to the active sites of the enzymes reducing their accessibility. This presence helps control enzyme activity effectively managing the breakdown of food materials.

Pathways

CMx1/CMx3 inhibition of trypsin and alpha-amylase is linked to digestive regulation pathways. This regulation impacts the digestive efficiency of organisms consuming the plant material. Trypsin and alpha-amylase are integral to the proteolytic and amylolytic pathways. CMx1/CMx3 has indirect relationships with proteins involved in these pathways such as protease inhibitors that work in a coordinated manner to maintain balance in digestive enzyme activities.

Alterations in CMx1/CMx3 activity can relate to digestive disorders and malabsorption syndromes. This connection occurs because improper inhibition or activation of trypsin and alpha-amylase may lead to imbalanced digestion and nutrient absorption issues. CMx1/CMx3 shares relevant interactions with other protease inhibitors which also participate in modulating enzyme activity in the digestive system playing a part in maintaining gut health.
