In SilicoAnalysis for Transcription Factors WithZn(II)2C6Binuclear Cluster DNA-Binding Domains inCandida albicans

Abstract

A total of 6047 open reading frames in theCandida albicansgenome were screened forZn(II)2C6-type zinc cluster proteins (or binuclear cluster proteins) involved in DNA recognition. These fungal proteins are transcription regulators of genes involved in a wide range of cellular processes, including metabolism of different compounds such as sugars or amino acids, as well as multi-drug resistance, control of meiosis, cell wall architecture, etc. The selection criteria used in the sequence analysis were the presence of theCysX2CysX6CysX5-16CysX2CysX6-8Cysmotif and a putative nuclear localization signal. Using this approach, 70 putativeZn(II)2C6transcription factors have been found in the genome ofC. albicans.
