description	Enzyme Active Site Engineering - Engineer enzyme: identify active site residues, predict pocket, analyze binding site, and predict mutations. Use this skill for enzymology tasks involving predict functional residue run fpocket get binding site by id pred mutant sequence. Combines 4 tools from 3 SCP server(s).

Enzyme Active Site Engineering

Discipline: Enzymology | Tools Used: 4 | Servers: 3

Description

Engineer enzyme: identify active site residues, predict pocket, analyze binding site, and predict mutations.

Tools Used

• predict_functional_residue from server-1 (sse) - https://scp.intern-ai.org.cn/api/v1/mcp/1/VenusFactory
• run_fpocket from server-3 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/3/DrugSDA-Model
• get_binding_site_by_id from chembl-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/4/Origene-ChEMBL
• pred_mutant_sequence from server-3 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/3/DrugSDA-Model

Workflow

1. Identify active site residues
2. Predict catalytic pocket
3. Get binding site info from ChEMBL
4. Predict improved mutant sequences

Test Case

Input

{
    "sequence": "MKTIIALSYIFCLVFA"
}

Expected Steps

1. Identify active site residues
2. Predict catalytic pocket
3. Get binding site info from ChEMBL
4. Predict improved mutant sequences
