Part F - Identifying conserved residues from the BLAST alignment If an amino acid is found at the exact same location in the alignment of two homologous proteins, that amino acid is said to be "absolutely conserved." An amino acid type can also be conserved at a given position. Using the BLAST sequence alignment above, sort aligned residues into the appropriate categories.

### Sequence Analysis

After determining the full amino acid sequence of FABP6, a BLAST search was conducted against the Protein Data Bank (PDB) to find similar structures. One structure was found to be 59% identical to the FABP6 sequence. The alignment of your protein (FABP6) is shown in blue, while the homologous structure (3ELX) is displayed in red.

**BLAST Alignment Results:**
- **Expect Score:** \(4 \times 10^{-42}\)
- **Identities:** 69/116 (50%)
- **Positives:** 88/116 (75%)

### Alignment Explanation

- **Identical Amino Acids:** Shown in black.
- **Similar, Non-identical Amino Acids:** Noted by a "+" symbol.

The sequences are aligned to show overall gaps, indicating differences in the sequences but with substantial similarities.

This alignment can help in understanding the functional and structural similarities between the two protein sequences,
