The Saccharomyces cerevisiae CDC43 gene product is involved in establishing cell polarity during the cell-division cycle. When grown at restrictive temperatures, temperature-sensitive cdc43 mutants are unable to form buds and display delocalized cell-surface deposition [Adams et al., J. Cell Biol. (1990) in press]. We have isolated a cdc43-complementing plasmid from a yeast genomic-DNA library ...
متن کاملThe helix-turn-helix motif of bacterial insertion sequence IS911 transposase is required for DNA binding.
The transposase of IS911, a member of the IS3 family of bacterial insertion sequences, is composed of a catalytic domain located at its C-terminal end and a DNA binding domain located at its N-terminal end. Analysis of the transposases of over 60 members of the IS3 family revealed the presence of a helix-turn-helix (HTH) motif within the N-terminal region. Alignment of these potential secondary...
متن کاملHTHquery: a method for detecting DNA-binding proteins with a helix-turn-helix structural motif
SUMMARY HTHquery is a web-based service to determine if a protein structure has a helix-turn-helix structural motif which could bind to DNA. It is based on a similarity with a set of structural templates, the accessibility of a putative structural motif and a positive electrostatic potential in the neighbourhood of the putative motif. A set of scores are computed, based on each template, using ...
متن کاملThe solution structure of the Mu Ner protein reveals a helix-turn-helix DNA recognition motif.
BACKGROUND The Mu Ner protein is a small (74 amino acids), basic, DNA-binding protein found in phage Mu. It belongs to a class of proteins, the cro and repressor proteins, that regulate the switch from the lysogenic to the lytic state of the phage life cycle. There is no significant sequence identity between Mu Ner and the cro proteins of other phages, despite their functional similarity. In ad...
