CHAVEZ, RENATO et al. The acetyl xylan esterase II gene from Penicillium purpurogenum is differentially expressed in several carbon sources, and tightly regulated by pH. Biol. Res. [online]. 2004, vol.37, n.1, pp.107-113. ISSN 0716-9760.

The expression of the acetyl xylan esterase II (axeII) gene from Penicillium purpurogenum is repressed by glucose and induced by xylan, as well as to a small degree by xylose and xylitol. This gene is expressed at neutral pH, but not under alkaline or acidic conditions, in agreement with previous findings for other xylanolytic genes of this organism. This is the first report showing pH regulation of an axe gene.

Keywords : acetyl xylan esterase; gene expression; Penicillium purpurogenum .
