Abstract

Transcription of the 3-phosphoglycerate kinase (PGK)-encoding gene (pgk1) of Trichoderma reesei results in two transcripts due to two main transcription start points (tsp) which are differentially regulated during the growth cycle. The nucleotide sequence of the promoter reveals a number of putative regulatory elements present also in the PGK promoter of Saccharomyces cerevisiae: a 20-nt long sequence similar to the CTTCC-repeat region of the upstream activating sequence UAS, the eukaryotic heat-shock consensus sequence, HSE, and a putative eukaryotic cAMP regulatory sequence. The functionality of the putative HSE sequence was examined, but no clear effect could be seen on the total amount of pgk1 mRNA at elevated temperatures nor on transcription initiation from the upstream tsp, preceded by the HSE sequence.
