Protein

Sporulation-specific glucan 1,3-beta-glucosidase

Gene

SPR1

Organism
Saccharomyces uvarum (strain ATCC 76518 / CBS 7001 / CLIB 283 / NBRC 10550 / MCYC 623 / NCYC 2669 / NRRL Y-11845) (Yeast) (Saccharomyces bayanus var. uvarum)
Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Protein inferred from homologyi

Functioni

Probably involved in the processes of spore formation and contributes to ascospore thermoresistance by participating in the morphogenesis of ascospore walls. The enzyme may do this by modifying glucan linkages in the developing ascospore wall, thus strengthening it or lending it plasticity (By similarity).By similarity

Catalytic activityi

Successive hydrolysis of beta-D-glucose units from the non-reducing ends of (1->3)-beta-D-glucans, releasing alpha-glucose.

100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
