Notes:
A gene homologous to Saccharomyces cerevisiae PMR1 has been cloned in the methylotrophic yeast Hansenula polymorpha. The partial DNA fragment of the H. polymorpha homologue was initially obtained by a polymerase chain reaction and used to isolate the entire gene which encodes a protein of 918 amino acids. The putative gene product contains all ten of the conserved regions observed in P-type ATPases. The cloned gene product exhibits 60·3% amino acid identity to the S. cerevisiae PMR1 gene product and complemented the growth defect of a S. cerevisiae pmr1 null mutant in the EGTA-containing medium. The results demonstrate that the H. polymorpha gene encodes the functional homologue of the S. cerevisiae PMR1 gene product, a P-type Ca2+-ATPase. The DNA sequence of the H. polymorpha homologue has been submitted to GenBank with the Accession Number U92083. © 1998 John Wiley & Sons, Ltd.
