Example sentences for: alpha-amylase

How can you use “alpha-amylase” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • This hypothesis is based on findings that only those glucose analogs that are believed to be substrates for phosphorylation by hexokinases are effective in repressing alpha-amylase expression [ 37 ] . However, the role of hexokinases in sugar responses remains under debate [ 38 39 40 ] .

  • Proteins postulated to act in control of at least some sugar-regulated processes include hexokinases [ 31 32 33 34 ] and SNF1-related protein kinases [ 35 36 ] . Hexokinases have been suggested to play a role in sugar repression of alpha-amylase activity.

  • For example, sugars repress a gibberellin-dependent pathway for alpha-amylase expression in barley embryos [ 30 ] .

  • Increasing sugar levels have been shown to repress expression of alpha-amylases in rice seedlings [ 24 ] and suspension culture cells [ 25 ] . Studies using barley embryos provide evidence for the existence of independent glucose and disaccharide signaling mechanisms in the regulation of alpha-amylase expression [ 26 ] . Sugar regulation of alpha-amylase expression has also been shown to occur at multiple levels.

  • Sugar levels affect not only alpha-amylase transcript levels [ 24 25 ] , but also mRNA stability [ 27 28 ] and protein transport and turnover [ 29 ] . Sugar-signaling pathways may also interact with other signaling pathways in the control of alpha-amylase activity.
