title: [Biochemical response of recombinant Hansenula polymorpha strains to oversynthesis of homologous dioxyacetone kinase and bacterial beta-galactosidase].
abstract: Changes in the activities of key enzymes responsible for utilization of methanol by recombinant strains of methylotrophic yeasts H. polymorpha R22-2B and H. polymorpha LAC-56 grown in a chemostat are described. The strain R22-2B displaying a high activity of dioxyacetone kinase had also a high activity of formaldehyde dehydrogenase, which increased the rate of dissimilation of formaldehyde. There was a decrease in ATP concentration in the strain LAC-56 oversynthesizing beta-galactosidase from Escherichia coli; this effect decreased the rate of assimilation of formaldehyde.
