The endoxylanases from family 11: computer analysis of protein sequences reveals important structural and phylogenetic relationships.
Eighty-two amino acid sequences of the catalytic domains of mature endoxylanases belonging to family 11 have been aligned using the programs MATCHBOX and CLUSTAL. The sequences range in length fromExpand

Penicillium purpurogenum produces several xylanases: purification and properties of two of the enzymes.
The fungus Penicillium purpurogenum produces several extracellular xylanases. The two major forms (xylanases A and B) have been purified and characterized. After ammonium sulfate precipitation andExpand

The xylanolytic enzyme system from the genus Penicillium.
In nature, there are numerous microorganisms that efficiently degrade xylan, a major component of lignocellulose. In particular, filamentous fungi have demonstrated a great capability for secreting aExpand

Culture conditions for enhanced cellulase production by a native strain of Penicillium purpurogenum
A cellulolytic wild-type strain of Penicillium purpurogenum was isolated from a soil sample in southern Chile. It grew best at 28°C from an inoculum of 4×107 spores/100 ml medium. HighestExpand

Differences in expression of two endoxylanase genes (xynA and xynB) from Penicillium purpurogenum.
A number of xylanolytic microorganisms secrete to the medium several molecular forms of endoxylanases. The physiological function of these isoforms is not clear; one possibility is that they areExpand

An α-l-arabinofuranosidase from Penicillium purpurogenum: production, purification and properties
Penicillium purpurogenum secretes arabinofuranosidase to the growth medium. Highest levels of enzyme (1.0 U ml−1) are obtained when l-arabitol is used as carbon source, while 0.85 and 0.7 U ml−1 areExpand

Purification and characterization of two acetyl xylan esterases from Penicillium purpurogenum
Penicillium purpurogenum produces several enzymes active in xylan hydrolysis, of there, the acetyl xylan esterase (AXE) activity secreted by the fungus has now been studied. The amount of activityExpand

Proteomic analysis in non-denaturing condition of the secretome reveals the presence of multienzyme complexes in Penicillium purpurogenum
Proteins secreted by filamentous fungi play key roles in different aspects of their biology. The fungus Penicillium purpurogenum, used as a model organism, is able to degrade hemicelluloses andExpand

Electrophoretic karyotype of the filamentous fungus Penicillium purpurogenum and chromosomal location of several xylanolytic genes.
The electrophoretic karyotype of the filamentous fungus Penicillium purpurogenum has been resolved. Using contour-clamped homogeneous electric field gel electrophoresis, five chromosomal bands wereExpand
