HMM PD00008

Back to List of HMMs

Symbol: CC1_Sac_PD

Name: Sac phosphatase domain

Description

Based upon the crystal structure of yeast SAC1, the yeast SAC1 has two structure domains: SacN and catalytic domain [1] (see the sequences in supplementary materials). The SacN ranges from 1-181; the catalytic phosphatase domain ranges from 182-504.

When using the HMM/PSSM profiles of public databases to determine the region of phosphatase domain, they gave different regions from the region determined from the crystal structure paper:

• Pfam database: Syja_N (PF02383), 56-343
• CDD database: 1) Cdd:pfam02383, 55-348, 2) Cdd:COG5329, 3-578
• SMART: no hit

In brief, Pfam profile contains part of SacN domain and part of the phosphatase domain; COG profile contains both SacN and the catalytic phosphatase domain.
