Mannosyl Transfer in Cryptococcus laurentii
Abstract A particle-bound enzyme from the fungus imperfectus Cryptococcus laurentii var. flavescens (NRRL Y-1401) mediates transfer of mannosyl units from GDP-mannose to endogenous primer. The enzyme requires divalent cations for activity. The pH optimum is 7.5 and the apparent Km for GDP-mannose is 0.14 mm. A polysaccharide fraction that is associated

Heteroglycan Synthesis in Cryptococcus laurentii
Abstract An enzyme preparation from Cryptococcus laurentii catalyzes the transfer of glycosyl units from sugar nucleotides to exogenous acceptor resulting in the stepwise synthesis of a heteroglycan with the following structure: 2-O-α-d-mannosyl-6-O-α-d-mannosyl-3-O-α-d-mannosyl-(2-O-β-d-xylosyl-)-d-mannose. The same enzyme preparation transfers d-[14C]

Multiple Mannosyl Transferases in Cryptococcus laurentii
A particle-bound enzyme preparation from the fungus imperfectus Cryptococcus laurentii var. flavescens (NRRL Y-1401) catalyzes transfer of mannosyl units from GDP-mannose to mono- and oligosaccharide acceptors. Four separate enzymes can be differentiated by some or all of the following criteria: pH optimum, Km values for GDP-mannose, acceptor ...

Phytase activity inCryptococcus laurentiiABO 510 [PDF]
Ten Cryptococcus strains were screened for phytase activity, of which the Cryptococcus laurentii ABO 510 strain showed the highest level of activity. The cell wall-associated enzyme displayed temperature and pH optima of 62 degrees C and 5.0, respectively.
